- A few more cleanups.

Slick 7.x-2.0-dev, 2016-03-23
-----------------------------
- #2692887: Remove redundant asNavFor selectors.
- #2692569: Use grouping to simplify skins.
- The following functions are moved out of slick.admin.inc to match D8 into

- Removed trivial slick_classes: .slick--center, .slick--float, .slick--ondemand
  classes.

Slick 7.x-2.0-dev, 2016-01-18
-----------------------------
- #2647968 by lardfw: Slick not showing block reference field as option for
  caption
- #2637470 by kyletaylored: Support PHP 7

Slick 7.x-2.0-dev, 2015-12-19
-----------------------------
- #2637706 by kyletaylored: Support when using Slick as field in BEAN/Taxonomy.

Slick 7.x-2.0-dev, 2015-12-12
-----------------------------
- Fixed for nested slicks with videos. The videos should be turned off when
  either the nested slick, or the parent slick, with/without asnavfor, is
  changing.

Slick 7.x-2.0-dev, 2015-12-11
-----------------------------
- Updated for v1.5.9 with the new option useTransform.
- Fixed for Navbar compatibility.

Slick 7.x-2.0-dev, 2015-12-07
-----------------------------
- Updated slick.api.php with more samples, quick and asnavfor ones.
- Respected empty centerPadding ('0' or '') to allow pure CSS controlled styled
  rather than inline style. This removed inline padding: 0px, so CSS do not have
  to use !important to override it.

Slick 7.x-2.0-dev, 2015-12-02
-----------------------------
- Issue #2623396 by dalemoore, Spanners: Really wide View edit screen in admin
  overlay
- Removed too specific lines from most skin CSS, such as color, weight, etc.
  where appropriate.
- Fixed for Fullscreen skin thumbnail nav with asNavFor.
- Removed over-specificity from slick.theme.css due to expected nested slicks
  as it turned out to break some builtin layouts like Full width. Your overrides
  should not be affected as the slick.theme.css is now less specific.

Slick 7.x-2.0-dev, 2015-11-28
-----------------------------
- Cleaned up useless lines.
- Fixed for FC nested slicks with iframe and media icons visibility.

Slick 7.x-2.0-dev, 2015-11-26
-----------------------------
- Added more description on Slick Grid or multiple rows carousel.

  against Bartik.
- Added "Lazy iframe" option to have truly lazyloaded iframes for Media and FC
  to speed up loading time before JS fired.
- Moved media icons and iframes after the image to allow using CSS siblings
  selector (~) for spinner visibility in combination with [data-lazy] which is
  removed when the image is fully loaded, e.g.:
  .media-icon--spinner { display: none; }
  img[data-lazy] ~ .media-icon--spinner { display: block; }

Slick 7.x-2.0-dev, 2015-11-21
-----------------------------
- #2546614 by Dr.Osd: Colorbox integration has broken iframe width

Slick 7.x-2.0-dev, 2015-11-16
-----------------------------
- Disabled thumbnail navigation if items < 2 to avoid gargantuan broken single
  thumbnail nav since it will be unslicked anyway. The good thing is this allows
  a combination of asnavfor at one page and/or a single image or slideshow
  display at another without creating different fields.
- Added caching per language to reflect the change at Slick Views per 2611838.

Slick 7.x-2.0-dev, 2015-11-07
-----------------------------
- #2600970 by dalearyous: remove the image zoom or magnification for center
  image slick carousel
- #2610348 by IckZ: Colorbox not working when only one image is displayed.
- #2596599 by mparker17: Add link to settings page in .info file
  Oops, sorry, attribution!
- #2596599 by mparker17: Add link to settings page in .info file

Slick 7.x-2.0-dev, 2015-9-30
----------------------------
- Clarified several descriptions on form items, and elsewhere.
- Moved some contents of slick.field.inc into slick.global.inc to share with
  Slick views for its future enhancement with Media file like Slick fields.
- Added configurable optional core slick-theme.css and module slick.theme.css
  which are normally included by default along with skins.
- Removed problematic Editor links for Media file, since it is not displayed
  when cache enabled anyway.

Slick 7.x-2.0-dev, 2015-9-12
----------------------------
- #2567233 by espacecode: Grid options require Visible slides, otherwise no
  slides shown anymore.
  Added more information on Grid options about requiring Visible slides.

Slick 7.x-2.0-dev, 2015-9-11
----------------------------
- Issue #2566799 by quasi: Image linked to content should not be
  removed without colorbox/photobox.
- Cleaned up README.txt, and a few other things.

Slick 7.x-2.0-dev, 2015-9-09
----------------------------
- Merged DRY stuffs into slick_get_image().

Slick 7.x-2.0-dev, 2015-9-08
----------------------------
- Added hook_uninstall() since we now have a variable to delete.
- Added a configurable option using slick_ui.module to toggle slick admin css
  which can be accessed at: admin/config/media/slick/ui
- #2553385 by gausarts, xtfer: Slick CSS admin compatibility with contrib admin
  themes.

Slick 7.x-2.0-dev, 2015-9-07
----------------------------
- Made slick admin css optional. Execute the following anywhere once to disable
  slick admin stylings:
  variable_set('slick_admin_css', FALSE);

Slick 7.x-2.0-dev, 2015-9-06
----------------------------
- #2553385 by gausarts, heliogabal, esolitos: Slick CSS admin compatibility with
  contrib admin themes
  Added fixes for Ubuntu with FF 40 and Chrome 45, and a few cleanups.

Slick 7.x-2.0-dev, 2015-9-03
----------------------------
- #2553385 by gausarts, heliogabal, esolitos: Slick CSS admin compatibility with
  contrib admin themes

Slick 7.x-2.0-dev, 2015-9-02
----------------------------
- Added a warning to Cache option: Only enable it when all is done, otherwise
  cached options will be displayed while changing them.
- Merged slick-current and arrows fixes into setPosition.

Slick 7.x-2.0-dev, 2015-8-28
----------------------------
- Simplified cache option description.

Slick 7.x-2.0-dev, 2015-8-27
----------------------------
- Moved slick stuffs out of unslick at template_preprocess_slick().
- Updated slick.load.min.js to abandon inaccessible activeBreakpoint approach:
  o Removed broken activeBreakpoint options, and use setPosition event instead.
  o Moved all setCurrent to also be placed at setPosition event.
  Note: setPosition was avoided so far because it is executed a lot, at least 4
  times on init, but appears to be the guy to fix a few known issues at one
  place with slick-current and arrows visibility with responsive options and
  asNavFor.
  Both are still kept till fixed by core, and finally dropped from the module.
- Fixed for Notice: Undefined index: view_mode in
  _slick_fields_field_formatter_settings_form() (line 224... due to the latest
  admin Slick fields rearrangement.
- Fixed for Notice: Undefined index: cache in slick_build() (line 376..

Slick 7.x-2.0-dev, 2015-8-25
----------------------------
- Fixed for useless Media file entity editor links being cached for anonymous.
- Improved Slick fields cache routines.
- Fixed for slick-current with adjacent slicks with/without slick_wrapper,
  block__no_wrapper/ views_view_no_wrapper, etc. No wonder core fails with it :(
- Dropped slide--current, and pushed slick-current s planned instead to
  reduce dup classes. If you use "slide--current", be sure to change it to
  "slick-current". The workaround is still kept, only easier to drop later when
  fixed.

Slick 7.x-2.0-dev, 2015-8-23
----------------------------
- Added cache fallbacks:
  o fetching from fresh contents if expiration time is provided, useful for
    dynamic contents which value freshness.
  o fetching from stale ones if "Persistent" is selected, useful for static
    contents which value cache lifetime better than freshness.
- Changed cache keys to a more reliable cid since keys will append active theme
  which adds additional check.
- Added configurable #cache property to slick_build() to cache render array.
- Merged similar field formatter and Views default settings into
  slick_get_global_default_settings().
- Merged reusable form elements across field formatter and Views via
  slick_get_top_elements() and slick_get_elements().

Slick 7.x-2.0-dev, 2015-8-19
----------------------------
- #2553385 by gausarts, esolitos: Slick CSS admin compatibility with contrib
  admin themes.
- Fixed for arrows visibility with responsive options due to inaccessible
  activeBreakpoint flag.
- Fixed for Photobox "infinite true + slidesToShow > 1" incompatibility at the
  price of dup thumbnails which however can be disabled by "thumbs: false".
  This is less problematic than broken Photobox links.
- Deprecated the following functions:
  o _slick_fields_format_image() for slick_format_image().
  o _slick_fields_format_media() for slick_format_media().
  o _slick_fields_format_field_collection() for slick_format_field_collection().
- Moved the contents of slick_fields includes files into core to re-use them
  across field formatters and Views without hard dependency for slick_fields.
  This is also to smoothen the transition out to Slick 3.x.
- Added support for iframe only aspect ratio.
- Added support for Youtube or Vimeo url using plain text field within file
  entity of type image to display a video overlay over the main image
  background.
  Provided as currently file entity doesn't support nested files.
- Added slick_get_grid_elements() and slick_build_grids() to reuse grid for
  field formatter and Views.
- Removed Photobox "data-src" thumbnails to use global "data-thumb" instead.
- Added slick_get_admin_assets() to re-use the admin assests across field
  formatter and Views.

Slick 7.x-2.0-dev, 2015-8-7
---------------------------
- Simplified slick.colorbox.css to use "colorbox-on--media" rather than
  separate "colorbox-on--audio" + "colorbox-on--video" for the video/audio
  colorbox body classes.
- #2546614 by stefan.korn: Colorbox integration iframe width?
- Removed 'slick-nav' classes since 'slick-arrow' was added at v1.5.6. If you
  use 'slick-nav', be sure to update it to 'slick-arrow'.
- Removed useless 'respondTo' option from responsive since it is always ignored/
  hard-coded by core: _.respondTo = _.options.respondTo || 'window';
- Fixed for video switcher image not being hidden when switched and a single
  image, not carousel.
- Added support to merge dots to .slick__arrow via appendDots: .slick__arrow, to
  have this style: < o o o o o o o >
- Added "Image linked to content" option to the "Media switcher" option to allow
  aggregated small slick fields linked to their host entity while using the
  Field formatter, not Views. E.g.: homepage small collages linked to contents.

Slick 7.x-2.0-dev, 2015-7-4
---------------------------
- Fixed a rare edge case with improper/broken data_export_import media files.

Slick 7.x-2.0-dev, 2015-6-30
----------------------------
- Allowed re-using slik.media.min.js outside slick.
- Fixed bad markups (h2 > p) with Media slide title when plain text has HTML
  filter enabled.
- Fixed regression with FC thumbnail caption plain text not displayed with the
  new EMW.
- Fixed regression with FC slide title not displayed with the new EMW.
- Fixed regression with Fullscreen single item/ unslick not displayed since no
  slide wrappers in use.
- Added support for Media multiple slide links, e.g.: Read more | Contact us.
- Cleaned up field markups for Media/FC 'slide_caption' fields by default unless
  'markup' set to TRUE. Use hook_slick_fields_default_settings_info_alter(), or
  check the new option 'Keep field markups'  to keep deep field markups
  (.field > .field-items > .field-item). Existing markups won't be affected till
  Slick field settings re-saved.
- Cleaned up field markups for Media/FC 'slide_link' fields since it is cleaner
  to just have A tags within .slide__link DIV.
- Renamed shit to s***, fire to f*** and rose to r***.
  "And the f*** and the r*** are one." Little Gidding -- TS Eliot.
- Renamed slick_fields_inline_css_output_info() to slick_inline_css_info().
- Removed Fullscreen inline css building out of the field loop, and moved it
  into slick_get_inline_css() instead since inline css is such an edge case.
- Simplified admin repetitive lines for readability and consistency.

Slick 7.x-2.0-dev, 2015-6-23
----------------------------
- Fixed regression with Fullscreen CSS output for Media and FC fields.
- Moved all skin Fullwidth and Fullscreen stuffs out of the main slick.theme.css
  into its own CSS: slick.theme--full.css to reduce clutters at the main CSS and
  also allows easy overrides at this particular skin CSS file.
  This file is re-used for both Fullscreen and Fullwidth skins.
  This also removes redundant selectors where '.slide__constrained' is used.
  It should be safe, whether you override or not, as it is less specificity
  which means your overrides will always win.
- Fixed for text only slides without images, that is, only applies absolute
  positioning when a slide layout is explicitly chosen.
- #2510528 by swinglo: array_merge(): Argument #2 is not an array dans
  template_preprocess_slick_item()

Slick 7.x-2.0-dev, 2015-6-22
----------------------------
- Fixed for most DRY with repetitive field tasks.
- Fixed regression 'slick__arrow--' modifier class which should be like beta2.
- Fixed for ESLint complaints to some extent, ignored coder_sniffer for JS.
- Fixed Media failing file_view_file() when the formatter is not expected.
  theme_file_entity_file_video() may take over other media, and cause the
  expected youtube/vimeo/soundcloud fails given the same weight 0 (default).
- Fixed regression with FC edge-cases with deleted, or non-existent main
  slide/stage image.
- Moved thumbnail out of theme_slick_media() business since it is always
  theme_image_style().
- Removed wasted settings.
- Changed custom slide 'classes' to 'slide_classes' to reduce duplicate keys.
- Added 'slick_classes' settings to remove shit classes, use
  hook_slick_element_default_settings_info_alter() to disable it.
- Post beta2 changes.

Slick 7.x-2.0-dev, 2015-6-19
----------------------------
- Fixed for jQuery < 1.5 admin pages.
- Changed hard-coded divities at slick-item.tpl.php to have leaner markups when
  only one item given:
  o Wrapper prefixes/suffixes can be DIV, or UL if grid.
  o Content prefixes/suffixes can be DIV, or LI if grid.
  This removes four useless HTML tags with a single item slick/unslick while
  allowing more complex layout composition for more items.
  These flexible wrappers are common to Views HTML list template.

- Fixed for slick.photobox.min.js, the slick-photobox class leaking if there are
  more than slicks even those without photobox.

- Updated slick.media.tpl.php to move the item_prefix and item_suffix outside
  the item. This allows proper display of a single item slick (unslick) given
  proper divities.

- Removed FC 'aspect_ratio_overlay' option, as it complicated things.
  The two solidified options for the aspect ratio overlays/nested slicks are:
  o Managed by the host entity (FC), requires 'Rendered file' formatter.
    The File aspect ratio is manipulated from within the host directly.
  o Managed by the File field itself outside FC, best with Slick formatter.
    The File aspect ratio is manipulated within its own View mode outside FC.

  This means FC:
  o overlays/nested are enforced to be just on XOR off.
  o field_type classes are dropped.
  o is simple just like regular Media file without nested slicks.

  Large background video is never implemented from the start as the doc comments
  at slik_fields.formatters.field_colletion line 50:
  // Large background video is not supported, any taker?
  And no taker so far, hence why this 'aspect_ratio_overlay' is dropped.

  The relevant classes are moved directly to the theme_slik_media() to reduce
  redundant CSS, previously within theme_slick():
    .slick--ratio--file
    .slick--ratio--field-collection

  The benefit is it solidifies layouts for a mix of image/audio/video files.
  Please see slick.media.css for more detailed changes, only if you overrode it.
  Although tested with several old overriden slick.media.css, and they display
  fine, be sure to check this change as it removed lots of redundant CSS rules.

- Refactored and simplified the slick aspect ratio handling.
- Fixed for Field collection nested slicks managed by the host entity (FC).
- Refactored and simplified Field collection part cutting down ~150 lines.

- Fixed slide--current class for the most complex slicks, i.e.: asNavFor with
  the main display containing nested slicks.

- Renamed not-clear .slick__capture (based on icon) class to .litebox.

- Renamed 'attach_slick_element' to more meaningful 'attach_slick_css'.
  Be sure to update it if you disable slick-theme.css.

- Renamed 'attach_module' to 'attach_module_js' to be more meaningful like
  'attach_module_css'. Prior to alpha, the CSS is part of 'attach_module'.
- Renamed #asnavfor key to #display accordingly.
  Changed theme_slick_media() variables 'asnavfor' to 'display' to reflect
  the proper/meaningful displays. Displays can be:
  o main (asnavfor)
  o thumbnail (asnavfor)
  o grid
  o overlay
  Be sure to update your variable if you already customize it.

- Refactored arrow down to reduce clutters at slick.tpl.php.
  If you customize it be sure to re-check it.
- Moved 'layout' key one level up from within captions to the item.

- Added media--ratio--on class to ease up managing ratio with the CSS, and
  get consistent styling for the mix of image/video/audio files within a slick.
  - Fixed collapsing slick overlay (nested slick) when only one item given.
  This change should reduce headache with a mix of image/video/audio in a single
  slick since they are now consistently styled with the same aspect ratio if so
  configured.

- Moved some contents of slick_fields.formatters.admin.inc to slick.admin.inc to
  be reusable across fields formatter, non-existent slick_entityreference, and
  the future slick_views, 3.x, without depending on slick_fields.
  Renamed the following functions:
  o _slick_fields_view_modes() to slick_get_view_modes()
  o _slick_fields_get_fc_fields() to slick_get_fc_fields()
  o _slick_fields_get_media_fields() to slick_get_media_fields()

- Removed slick_fields.formatters.global.inc, and moved its contents to
  core slick.fields.inc, and renamed the following functions:
  o _slick_fields_get_picture() to slick_get_image() and decluttered settings.
  o slick_fields_inline_css_skins() to slick_get_inline_css_skins().
  o slick_fields_get_default_settings() to slick_get_fields_default_settings().

  This change has two goals:
  o Allows re-using them for future field based Views with lazyLoad which is
    currently not supported, only Field formatter is.
  o Compatibility with the slick_media sub-module to reuse the same codebase
    for image to iframe switcher for field based Views for both 2.x. and 3.x.

- Renamed _slick_fields_get_media_thumbnail() to slick_get_media_thumbnail()
  since it is now in optional core file.
- Removed appendArrows option, since the module can do nothing, but hardcoded it
  which is already flexible enough to move around the arrows anywhere via CSS.
- Moved mousewheel and inline css attachments to slick_fields.
- Moved hook_permission() to the only module requiring it: slick_ui.module.
- Moved hook_help() to slick_ui.module to de-clutter main module file.
- Removed unused hook_libraries_info() since hook_library() suffices.
  Use slick_attach(), drupal_add_library(), or drupal_add_js() to add relevant
  assets with 3rd party integration. See the API, or slick_fields for samples.
- Post beta2 changes.

Slick 7.x-2.0-dev, 2015-6-6
---------------------------
- #2501507 by gausarts, rei: detect media module and jquery easing libraries
  Removed 'attach_media' from anything, except when 'media_switch' iframe-switch
  is explicitly chosen.
- Cleaned up a few doc and wasted lines.

Slick 7.x-2.0-dev, 2015-6-5
---------------------------
- Fixed for interrupted update process, when the process is reversed:
  running /update.php prior to clearing cache.
  The safe recommended process: clearing cache/registry -> /update.php.
  Temporarily put back the slick_optionset_ui.inc to avoid the issue till we
  figure out better process.

Slick 7.x-2.0-dev, 2015-6-4
---------------------------
- Reached the cleanup threshold of below 500 lines of the main module file.
- Removed _slick_optionset_defaults() in favor of slick_get_options(). One more
  function down, one more function down! Call 119, er 911.

Slick 7.x-2.0-dev, 2015-6-1
---------------------------
- Fixed slick_clean_options_info_alter() param.
- Fixed Field collection background image style when it is core image, not media
  file image type.
- Fixed typo at slick.api.php, and added a hook_slick_attach_load_info_alter().
- Moved slick_inline_css_skins() to slick_fields_inline_css_skins(), since it is
  only specific to fields, not views.
- Revived the "slick" class when it is "unslick" (a slideshow with a single
  slide/image -- i.e. when a content editor can not meet design specs), to get
  consistent CSS global styling. JS filters out the unslick instead.
- Moved specific backend-related functions to slick.admin.inc:
  o slick_get_responsive_options()
  o slick_clean_options()
  o slick_get_overridable_options()
- Moved specific theme-related functions to slick.theme.inc.

- #2497945 by gausarts: Move type juggling to backend only
  A slick_update_7007() is provided, but not effective for stored codes.

  Please re-save and re-export optionsets if you are a pre-alpha user who stored
  optionsets in codes before alpha release on 2015-3-31, or precisely before
  2015-3-2 commit: http://cgit.drupalcode.org/slick/commit/?id=f08c3b4

  Please ignore if you:
  o are a (pre-)alpha user who stored optionsets in codes after alpha.
  o never stored/exported optionsets in codes.

- Fixed single slide (unslick), and slick--float non-center slider, and a couple
  of cleanup.

Slick 7.x-2.0-dev, 2015-5-31
----------------------------
- #2497079: Move some sub-modules into separate projects
- Removed slick_devel and slick_example to go to: http://dgo.to/slick_extras
- Moved _slick_fields_get_media_thumbnail() to slick.extras.inc.

Slick 7.x-2.0-dev, 2015-5-30
----------------------------
- Added slick_update_7006() for a beta2 to avoid WSOD with slick_views removal.
- Removed libraries slick.easing, mousewheel, drupal.slick, and used one line JS
  array instead.
- Renamed libraries previously prefixed with "drupal" to be prefixed with
  "slick", e.g.: "drupal.slick.colorbox" to "slick.colorbox".

Slick 7.x-2.0-dev, 2015-5-29
----------------------------
- Removed slick_views, and moved it into http://dgo.to/slick_views
- #2497079: Move some sub-modules into separate projects
- Removed preprocess for theme_slick_wraper().
- Removed unused slick_get_setting() and slick_get_default_value() from
  slick.admin.inc.
- Fixed Field collection complication with view modes.
- Removed Sass for good. Thanks, and farewell, Sass!
- #2496005 by gausarts: Refactor slick_image_lazy to merge
  slick_image_formatter_lazy with it.

Slick 7.x-2.0-dev, 2015-5-28
----------------------------
- Fixed double loading of optionsets when using fields. Now only loaded once.
- Fixed edge case with media player positioning when not using the required
  aspect ratio.
- Fixed dotsClass JS error with asNavFor due to previous ignorant removal.

Slick 7.x-2.0-dev, 2015-5-27
----------------------------
- Moved aka off-loaded Slick fields admin settings into separate existing file
  slick_fields.formatters.admin.inc to reduce clutters at the module file.
- Removed mousewheel and slick.easing libraries registrations since the only one
  using them -- slick_add() -- was already removed, and slicks is just fine to
  continue using the ones registered via core hook_library().

Slick 7.x-2.0-dev, 2015-5-26
----------------------------
- Added key "inline css" at slick_slick_skins_info() to ease up registering a
  skin expecting inline CSS, not images, see fullscreen skin. Previously using
  a cumbersome hook_slick_inline_css_skins_info_alter().
- #2494421 by gausarts: Decouple export UI from the main module.

Slick 7.x-2.0-dev, 2015-5-25
----------------------------
- Removed over paranoid slick_filter_xss_admin() since Views UI has a more
  flexible "Rewrite results" option with selective tags stripping.
- Deprecated slick_get_default_value(), used slick_get_options() instead.
  The function is temporarily moved to slick.admin.inc for future deletion.
- Moved unused slick_optionset_load_all() into slick.admin.inc.
- Removed slick_add(), recommended to start using #attached with slick_attach()
  instead. This is never used and will be dropped at D8 anyway.
- Removed unused slick_image_default_styles(), including default slick image
  style, and moved it to slick_example.module instead.
- Removed useless _slick_gettype().

- #2494579 by gausarts: Merge slick.elements.inc contents into the module,
  and clean out unused functions.

Slick 7.x-2.0-dev, 2015-5-24
----------------------------
- Fixed for skin fullscreen after slick-wrapper removal.

Slick 7.x-2.0-dev, 2015-5-23
----------------------------
- #2479199 by gausarts: Drop wasted slick-wrapper when no asNavFor in use.

Slick 7.x-2.0-dev, 2015-5-19
----------------------------
- #2490528 by fragtom: Variable with doesn't display right.
  Notes:
- variableWidth is not compatible with slidesToShow > 1 if the container is
  smaller than the amount of visible slide widths.
  Best with uniform image heights to avoid jumpy empty space. Use scale height
  image effect, and keep width empty/dynamic.
  Useless with adaptiveHeight, and non-uniform image heights.
  Useless with slidesToShow > 1 if the container is smaller than the amount of
  visible slides.
  Troubled with lazyLoad ondemand. Use progressive or none instead.
- adaptiveHeight wants single visible slide (slidesToShow 1).
  Useless with variableWidth.


Slick 7.x-2.0-dev, 2015-5-13
----------------------------
- Fixed for slick_remove_wasted_dependent_options() not removing dependents.

Slick 7.x-2.0-dev, 2015-5-2
---------------------------
- #2481577 by fragtom: Lazy load is not supported with Picture enabled
  images
- Fixed skin fullwidth with .slide__constrained being overriden with relative
  position.

Slick 7.x-2.0-dev, 2015-4-29
----------------------------
- #2479117 by fragtom: Fade option is not compatible with slidesToShow > 1.
- Added meaningful info to the Fade option to avoid issue with multiple items.

Slick 7.x-2.0-dev, 2015-4-25
----------------------------
- #2477507 by sashken2: Original image for Colorbox display is ignored.

Slick 7.x-2.0-dev, 2015-4-24
----------------------------
- #2477065: jQuery.easing requirements
- Added more information at README.txt to rename jquery.easing.1.3.js to
  jquery.easing.min.js.
- Fixed trivial spaces at slick.api.php.

Slick 7.x-2.0-dev, 2015-4-14
----------------------------
- Fixed typo at slick.api.php.
- Fixed edge cases Media Youtube, Vimeo, Soundcloud disabled while being used.
- Fixed edge case Picture module disabled while being used by Slick.
- Added a simple coded slick example to slick.api.php.
- Added slick_build() to simplify building a slick programatically.

Slick 7.x-2.0-dev, 2015-4-11
----------------------------
- #2466073 by gausarts: Use data-slick to store options.
  Be sure to clear cache, or re-generate JS if aggregation is on.
- #2466327 by rHOnDO: Allow alterable caption HTML tags.
- Added slick_filter_xss_admin() to ease up extending allowed tags restrictively
  which can be set using variable_set('slick_allowed_tags', $allowed_tags).
  Be sure to clear cache.
- Fixed slick_example hook_views_api() api version from Bulk exporter.
- Updated slick.load.devel.js to test the options using data-slick.

Slick 7.x-2.0-dev, 2015-4-6
---------------------------
- Updated slick.load.min.js slide--current class to reflect the new grid option.
- Added info to Slick Views about the difference between Module grid and the
  library grid. The module Grid feature has been around before the Slick library
  officiallly supported it at Slick 1.5.
- Added options for builtin Grid system: rows and slidesPerRow.
- Updated the verticalScrolling option to verticalSwiping. Be sure to re-save it
  to pick-up the newly renamed option.
- Updated to Slick 1.5.

Slick 7.x-2.0-dev, 2015-3-31
----------------------------
- \o/ at last .... happy for a great Alpha release ;)
- Added various relevant useful info somewhere to clarify the intention.
- Added relevant info on sanitization at slick.theme.inc which should be handled
  by implementors since most are renderable array.
- Added sanitization on Slick Views slide captions.
- Updated slick_devel_preprocess_slick() to drop data-slick test to reflect its
  removal at Slick 1.5, see:
  https://github.com/kenwheeler/slick/issues/1058
- Fixed wrong name slick_inline_css_output_info() to use the actual module name
  slick_fields_inline_css_output_info().
- Added slick_fields_inline_css_output_info_alter() to modify the inline CSS
  outputs.
- #2461693 by rfnbnkr: asNavFor stopped working with AJAX loaded slicks.
- Moved sanitization for asnavfor_target to template_preprocess_slick().
- Fixed trivial edge cases with extra white spaces for asnavfor targets.
- Fixed line breaks after php tags.

Slick 7.x-2.0-dev, 2015-3-30
----------------------------
- Fixed both phpcs and coder false positive with list() skipped value.
- Fixed disappeared admin tooltip after AJAX which seemingly broke at some
  point.
- Fixed phpcs complains with Closing parenthesis of array declaration.
- #2459669 by emcniece: Handle non-init'd jQuery Update module settings.
- #2459657 by emcniece: Add better error message for missing files /
  improper library install.
- Updated SLICK_VERSION from 1.4 to 1.x to avoid chasing minor releases.
- Changed slick_attach() to move slick_arrows() and slick_dots() invocation till
  requested.

Slick 7.x-2.0-dev, 2015-3-21
----------------------------
- Fixed edge-case issues with deleted optionset while being used.

Slick 7.x-2.0-dev, 2015-3-14
----------------------------
- Changed "data-thumb" to be always available not only for dots thumbnail hover,
  but also for custom advanced works with arrows containing thumbnails as long
  as "Thumbnail style" option is provided. It is up to you to build such complex
  arrows. See the current customPaging implementation on how to manipulate dots
  with lazy-loaded thumbnails which appears on hovering dots. The similar
  technique is also applied to build Photobox thumbnail navigation. If you
  don't make use thumbnails dots, nor arrows, nor Photobox thumbnails, simply
  leave the option empty.
- Removed wasted slide--before and slide--after classes from
  Drupal.slick.setCurrent() since it is never implemented so far.
- Fixed skin arrows and dots not being recognized by slick_navigations(), and
  dropped it in favor of slick_dots() and slick_arrows() instead.
- Added slick_elements_info_alter(), slick_responsive_elements_info_alter(), and
  slick_options_info_alter() to allow modifying slick options and form elements
  by custom module after stable release without having to wait for the features
  to be added or another release. Or when a module wants to modify slick options
  internally such as when building a modular slick.
- Fixed for duplicated/cloned thumbnails being displayed at Photobox.

Slick 7.x-2.0-dev, 2015-3-10
----------------------------
- Added the bad boy verticalScrolling option to drag up and down the slide. Use
  slick_devel module to test it. "Ken tired of this":
  https://github.com/kenwheeler/slick/issues/1001
  If you want your feature request fullfilled, make him tired ;)
- Added info about the data-slick to be removed at Slick 1.5 to slick_devel.
  See https://github.com/kenwheeler/slick/issues/1058
  The data-slick is never used by the module unless for development purposes.
- Fixed autoplay for Photobox videos, and moved the Colorbox autoplay logic from
  JS to PHP to share between lightboxes.
- Removed thumbnail_hover DOM markups -- thumbnails which appear on hovering
  dots, and used data-thumb attributes managed by JS customPaging instead.

Slick 7.x-2.0-dev, 2015-3-9
---------------------------
- Updated slick_example asNavFor to not use field template for the main display.
- Removed extra ISSET checks by proper definitions in
  slick_get_element_default_settings().
- Removed wasted "slick--progressive" class, and only provided "slick--ondemand"
  class only if the lazyLoad is ondemand to keep the current fix with excessive
  height of dummy image.
- Removed wasted "slick--display--main" class, and only provide one if it has
  thumbnail navigation in companion with "slick--display--thumbnail".
  Split "media-icon--lightbox" rules from "slick.colorbox.css" into
  "slick.lightbox.css" to share icon stylings between Colorbox and Photobox.
- Deprecated "media-icon--colorbox" for the more generic "media-icon--lightbox".
- Updated slick-media.tpl.php to reflect the support for Photobox, adding
  variable $is_lightbox to check for either Colorbox or Photobox.
- Added Photobox integration.
- Removed Drupal.slick.thumbnail(), and moved the relevant slick-dots--thumbnail
  class to dotsClass option instead.
- Deprecated "slick__thumbnail" class in favor of "slick-dots--thumbnail".
  If you customized it, be sure to update to "slick-dots--thumbnail", as it will
  be removed at proper release. It is a problematic class, since dotsClass is
  actually alterable child element. However default "slick-dots" is the only
  class to rely on now as a child block level element. If you change the
  options, assumed you know how to handle them consistently anyway.
- Added skin description and breakpoints to the slick collection page at:
  admin/config/media/slick
- Added slick_navigations(), hook_slick_dots_info() and hook_slick_arrows_info()
  to add custom dots and arrows CSS programatically, similar to existing
  hook_slick_skins_info(), only without defaults and cares for CSS. It reduces
  repetitive tasks with different sets of re-usable arrows and dots skin assets.
- Added an alterable slick_fields_get_default_settings() to avoid database
  lookup just to check if a setting is already set, or not, reducing a few extra
  ISSET checks at frontend.

Slick 7.x-2.0-dev, 2015-3-5
---------------------------
- Fixed off-screen/ hidden dots with Fullscreen due to core negative margin
  -45px.
- Fixed Views admin preview with full screen skin by adding a min-height 320px.
- Fixed various pareview.sh complains, and a few resolvable false positives.
- Fixed CRUD typecasting with slick_optionset_save().
- Fixed various tests failures locally sans codespell.
- Added tests for simpletest based on flexslider.test, and corrected its
  failures. Due credit to Flexslider.
- Added hook_help().

Slick 7.x-2.0-dev, 2015-3-2
---------------------------
- Fixed arrows not being recognized for the nested slicks.
- Fixed JS settings typecast for slick_example_slick_default_presets().
- Fixed Undefined index: rtl in template_preprocess_slick().
- Fixed typecast values before storing. It doesn't affect slick, just cleanup.
- Removed mousewheel data when disabled. It doesn't affect slick, just cleanup.
- Removed useless options at slick_fields.module display Formatter form:
  optionset and optionset thumbnail labels.

Slick 7.x-2.0-dev, 2015-3-1
---------------------------
- Fixed left-over overridable options for Field collection.
- Fixed PHPCS complains with CSS multiline selectors leaving ignorable
  lowerCamel.
- Fixed edge case asNavFor selectors -- non-empty, but not-used, asNavFor from
  breaking the slide. When it has value, but not actually used, or forgot to
  have the thumbnails. Otherwise breaking the slide.
- Fixed arrows not being updated with different visibility and responsive
  options, as this is said left to implementor/module when arrows customized.
  With the fix, arrows are enforced, but updated accordingly based on option.
- Changed module_load_include() to form_load_include() or ctools_load_include()
  in the form context.
- Added options to override optionset to re-use one optionset for a few
  different common displays with/without: Arrows, Autoplay, Dots and Draggable.

Slick 7.x-2.0-dev, 2015-2-27
----------------------------
- Fixed un-styled checkbox for grouping at Views UI.
- Added relevant cursor to slick.theme.css for draggable slick: grab and
  grabbing.
- Changed dependencies on slick_example to make use of sub-modules instead.

Slick 7.x-2.0-dev, 2015-2-26
----------------------------
- Fixed missing dependency on Views for Slick example module.
- Fixed slick_example views with skin Rounded not being rounded due to option
  "Use field template" under "Style settings" was checked.
- Fixed cssEaseBezier value not being mapped from cssEaseOverride at Optionset
  UI as part of optimization to move some logic to backend.
- #2438041 by RAFA3L: - Fixed broken Views style plugin due to removal of
  files array from slick_views.info:
  files[] = slick_views_plugin_style_slick.inc
  Be sure to clear cache to bring it back. The mistake was after PHPCS fixes.
- Fixed edge cases for slide--current class by requesting anon parent selector
  with/without theme_slick_wrapper(), and with/without asnavFor.
- Optimized slick.elements.inc, and moved slick form elements from
  slick_get_options() to the plugin page - SlickOptionsetUi.class.php.
  The following functions are moved to slick.admin.inc:
  - _slick_easing_options()
  - _slick_css_easing_options()
  - _slick_css_easing_mapping()
- Fixed undefined $overlay_style notice with Field collection nested slicks.

Slick 7.x-2.0-dev, 2015-2-25
----------------------------
- Fixed various PHPCS complains, except the helpless CTools lowerCamel formats
  and CSS multiline selectors due to Sass bug :unix_newlines never applied, nor
  proper line break after decendant selectors.

Slick 7.x-2.0-dev, 2015-2-24
----------------------------
- Simplified slick.tpl.php markups for when only 1 item is available.
- Fixed slick.theme.css and slick.load.min.js to support nested slicks. Be sure
  to re-check your CSS with the new specifity introduced by nested slicks.
  Mostly related to .slide__caption and .slide__media classes e.g.:
  Before:
  .slide--caption--below .slide__caption {}
  After:
  .slide--caption--below > .slide__content > .slide__caption {}

  This allows child slicks within a slick to have proper skins, rather than
  being overridden by the parent slick.

- Fixed for nested slicks, slicks within a slick for Field collection and Views.
- Fixed RTL attributes from the .slick to .slick-slider to reflect Slick 1.4.

Slick 7.x-2.0-dev, 2015-2-20
----------------------------
- Changed admin assests to use slick.admin library. Clear cache if trouble to
  see the admin styling.
- Added slick.admin library.
- Changed slick.load.js, slick.media.js and slick.colorbox.js with their
  minified versions, slick.load.min.js, slick.media.min.js and
  slick.colorbox.min.js, respectively to save some bytes.

Slick 7.x-2.0-dev, 2015-2-17
----------------------------
- Updated to media_soundcloud 7.x-2.1 which removed ::getOEmbed method.
- Fixed module slick.theme.css being overriden by library slick-theme.css.
- Fixed media video/audio autoplay not being triggered when button play clicked.
- Fixed media video carousel being sluggish due to the browser always request
  iframe SRC even when empty (about:blank). The iframe is now removed and stored
  in memory instead, and only made available when a play button clicked.

- Updated slick.media.js to reflect the latest fix with afterChange.

Slick 7.x-2.0-dev, 2015-2-15
----------------------------
- Fixed slide--current class not being applied when total <= slidesToShow, that
  is when slick-center class is not really centered, and when asNavFor applies,
  and when afterChange always fails.

Slick 7.x-2.0-dev, 2015-2-14
----------------------------
- Added hook_slick_attach_info_alter() to alter slick_attach() before output.
- Updated slick.api.php for the new skin CSS and JS array.
- Fixed skin CSS overrides not being applied for multiple slick instances on the
  same page, by changing the array of skin CSS and JS to be keyed by file names
  rather than indeces. Relevant to Drupal 8 dynamic assets.
  If you don't override the skin CSS, the change is ignorable.
  Single instance or multiple without overriding skins are not effected.
  Unless you have multiple slick instances on the same page, previous overrides
  with indeces will still work though.
  The change now allows proper overrides and respect the orders accordingly, see
  hook_slick_skins_info_alter().
  If you have overridden the skin CSS, be sure to update it accordingly, see
  slick.api.php for the updated information.

- Fixed skin Fullscreen inline CSS for slick_fields.module for Media and FC.

- Fixed .slick__arrow parent selector relevant for Slick 1.4, see
  Drupal.slick.arrows().
  This core bug happens when total <= slidesTosShow and should be fixed by the
  implementor/module as the author suggested.
- Fixed for skin 3d back relevant to the latest fix with afterChange and proper
  data-slick-index.
- Updated slick.load.js to reflect the 1.4.1 fixes.

Slick 7.x-2.0-dev, 2015-2-3
---------------------------
- Added more info related to ROADMAP and current delvelopment status at README.
- #2418149 by nrutkowski: - Fixed for Slick 1.4 breaking changes.
- Updated to Slick 1.4 with more tests and cleanups.
- Fixed nullified edgeFriction due to typecast integer to float.
- Updated the rest of year CHANGELOG from 2014 to 2015.

Slick 7.x-2.0-dev, 2015-2-1
---------------------------
- Updated slick example to avoid Unslick and too large centerPadding which
  screws up slidesToShow at small breakpoints.
- Updated year CHANGELOG from 2014 to 2015.
- Removed useless merged.prevArrow + merged.nextArrow from slick.load.js since
  arrows already added by HTML whenever required.
- Added hook_requirements() to slick.install.
- Added thumbnail caption to slick_fields and slick_views like yahoo/youtube
  thumbnail captioning.


Slick 7.x-2.0-dev, 2015-1-30
----------------------------
- Please read below before upgrading to Slick 1.4:
  Breaking changes: https://github.com/kenwheeler/slick/releases/tag/1.4.0
  - slide - The default value of the slide option has been changed to blank.
    This means that slick will use any direct children as slides, without having
    to specify which tag or selector to target.
    Consequencies:
    * - Added direct child container within .slick to hold the slides, i.e.:
      .slick__slider. Previously slides are direct children of .slick container.
    * Slick consequently must be initilialized at .slick__slider, otherwise we
      always have one slide.
    * "slick__arrow" can not be placed within .slick container directly even
      with the previous workaround by adding a specific class, and different
      selector. To overcome this, added additional container .slick__slider
      within .slick, so that .slick__arrow is not fetched as part of slides.
    * focusOnSelect , e.g. with thumbnail navigation, will not work anymore, so
      .slick__slide class added automatically only when needed now.
    * All in all, this is mostly breaking asNavFor, so be sure to update the
      asNavFor selectors accordingly at Field formatter and Views pages, e.g.:
      Before: #slick-nodes targetting .slick container.
      After: #slick-nodes-slider (note "-slider") targetting .slick__slider.

      Or adding " .slick__slider" to your current selector should resolve, e.g.:
      Before: #slick-nodes
      After: #slick-nodes .slick__slider
      Apply it to both asNavFor Main and asNavFor Thumbnail.

      Or if you are using sub-modules, and unsure, simply check the new option:
      "asNavFor auto selector" at:
      - admin/structure/types/manage/CONTENT_TYPE/display
      - admin/structure/views/view/VIEW
      This will auto generate the proper asNavFor selectors accordingly instead.
      See README.txt for the new HTML structure

   - Methods replaced by events
     Consequencies:
     * Drupal.slick.callbacks dropped, encouraged to use events now, see
     slick.media.js.
     We can bring this callback back if any good reason other than placing
     it somewhere in the slick.load.js, only then it is not specific to library.

   - slick.css has been forked into two different files. slick.css is now the
     core functional slick css file, while slick-theme.css are the default
     styling.
     Consequencies:
     * slick-theme.css is optional, and only added if you have chosen a Skin.
     This is a great plus for advanced work, e.g.: use own arrow icons.

- Added "Unslick" option to disable Slick at a given breakpoint. Note, you can't
  window shrink this, once you unslick, you are unslicked.
- Added "asNavFor auto selectors" option to determine asNavFor selectors by the
  current field/view ID selectors automatically as opposed to manual selectors.
- Updated slick.load.js, slick.media.js to use events, not callback anymore.
- Updated slick.tpl.php, SlickOptionsetUi, etc. to deal with the breaking
  changes introduced at Slick 1.4.
  Be sure to update slick.tpl.php, etc., if already customized.
- Updated to Slick 1.4.

Slick 7.x-2.0-dev, 2015-1-29
----------------------------
- Added unslick option for Slick 1.4 to disable Slick at breakpoint.
- Added mobileFirst option for Slick 1.4.

- Added Slick example sub-module, be sure to have field_image and field_images
  as no fields installed by default, see admin/reports/fields.
- Fixed for slick_devel_preprocess_slick() applied globally.

Slick 7.x-2.0-dev, 2015-1-26
----------------------------
- Updated workarounds to become permanent, since core library leaves them to the
  implementors for various reasons, such as: mousewheel, arrows issues, etc.
- Added slick_devel.module to ease developing the latest features of the
  library.
- Updated data-slick-index reference to use static class with slide--N classes
  instead to make it compatible with slick 1.4 and below.
- Added edgeFriction option as Swipetoslide fix, requires slick 1.4.

Slick 7.x-2.0-dev, 2015-1-25
----------------------------
- Updated invalid index attribute to data-slick-index as per

  Default lazyLoad "on demand" may have issue to generate newly created images,
  causing 403.
  Maybe related to itok: https://www.drupal.org/drupal-7.20-release-notes
  Possible fixes without compromising security:

  and lazyLoad, since both _must inherit from the main settings.

  reveal it on hover, override and edit slick.theme--classic.css and replace

- Added mousewheel option to slick_fields.module.
- Fixed undefined index media_switch at slick_fields form.
- Changed 
 to 
  as the last fail safe against the problematic anonymous DIV slide option. It

  one now.

  settings as a single JSON object within the Slick container rather than
  regular JS settings in the .
- Simplified logic at module slick.js. JS should not do hard work with typecast
  or parse separate multiple data attributes, PHP does. JS is now ready to
  consume valid JSON object, or nothing. This is relevant where bunch of JS
  settings with responsive displays get in.
- Renamed module slick.js into slick.load.js, to avoid conflict with the library
  for debug purposes.
- Renamed slick.css into slick.skin.css, otherwise Drupal overrides the library.
- Renamed "theme" directory into "templates" for Drupal 8 auto discovery
  goodness.

  yet.
