* This will return a provided thumbnail image for a video.
*
* @param $field
* This is the field providing settings for the video thumbnail.
* @param $item
* This is the data returned by the field. It requires at the least to be an array with 'value' and 'provider'.
* $item['value'] will be the video code, and $item['provider'] will be the provider, such as youtube.
* @param $formatter
* This is the formatter for the view. This will nearly always be video_thumbnail.
* @param $node
* This is the node object containing the field.
* @param $no_link
* Optional. If FALSE, then we provide a link to the node.
* (In retrospect, this should have been $link, defaulting to TRUE.
* TODO: fix? problem though is that this goes deeper up the tree.)
* @param $options
* Optional array. This is to pass optional overrides. currently:
* $options['width'] and $options['height'], if provided, will override any field settings for the thumbnail w/h.
* $options['link_url'], if provided, will cause the thumbnail link to go to another URL other than node/nid. $no_link must be FALSE.
* $options['title'], if provided, will set the title of the link and image.
* $options['link_title'], if provided, will set the title of the link when no image is provided. otherwise, it defaults to 'See video'.
* $options['image_title'], if provided, will set the title attribute of the href link, defaulting to $options['link_title'].
* $options['image_alt'], if provided, will set the alt attribute of the href link, defaulting to $options['link_title'].
* $options['thumbnail_url'], if provided, will completely override the thumbnail image entirely.
* $options['attributes'], if provided, sets the attributes for the displayed image.
* $options['return_url'], if provided, simply returns the URL to the thumbnail.
* $options['raw'], if TRUE, will return the raw URL, assuming $options['return_url'] is also true.
* @return
* The thumbnail output.
