/**
 * Provides a list of TinyMCE plugins.
 *
 * Each plugin for TinyMCE must provide an array of properties containing
 * information about the plugin. At minimum, plugins must provide a path and
 * file location so that TinyMCE may add the plugin. Available properties for
 * each plugin include:
 *
 * - location: Required for all external plugins. String path to the plugin
 *   directory relative to the Drupal installation root. Do not include a
 *   trailing slash.
 * - file: Required for all external plugins. String file name of the plugin in
 *   the "location" directory.
 * - internal: Boolean value indicating if the plugin is part of the compressed
 *   TinyMCE library package and already loaded on all instances. If TRUE,
 *   the "location" and "file" properties are not needed.
 * - css: An array of CSS files that should be added by TinyMCE. These files
 *   are used only when TinyMCE is using an iframe wrapper around its content.
 *   If a plugin needs to include CSS for inline and iframe versions, it should
 *   add its CSS via TinyMCE's JavaScript TinyMCE.addCss() method.
 * - enabled callback: String containing a function name that can determine if
 *   this plugin should be enabled based on the current editor configuration.
 *   See the hook_tinymce_PLUGIN_plugin_check() function for an example.
 * - buttons: An array of buttons that are provided by this plugin. Each button
 *   should by keyed by its TinyMCE button name, and should contain an array
 *   of button properties, including:
 *   - label: A human-readable, translated button name.
 *   - image: An image for the button to be used in the toolbar.
 *   - image_rtl: If the image needs to have a right-to-left version, specify
 *     an alternative file that will be used in RTL editors.
 *   - image_alternative: If this button does not render as an image, specify
 *     an HTML string representing the contents of this button. This alternative
 *     will only be used in the administrative section for assembling the
 *     toolbar.
 *   - attributes: An array of HTML attributes which should be added to this
 *     button when rendering the button in the administrative section for
 *     assembling the toolbar.
 *   - multiple: Boolean value indicating if this button may be added multiple
 *     times to the toolbar. This typically is only applicable for dividers and
 *     group indicators.
 *   - required_tags: If this button requires certain HTML tags to be allowed,
 *     specify an array of tags.
 * @return array
 *   An array of plugin definitions, keyed by the plugin name.

 *   being loaded.
