 * NGG registers its shortcodes using Shortcodes::add($tag, $callback)

 * We do this for the following reason:
 *
 * NGG is used with a wide variety of third-party themes and plugins. Some of which, do things
 * a little unorthodox, and end up modifying the markup generated by the shortcode, which breaks
 * the display for our users.
 *
 * Rather than having to explain to our userbase, "you shouldn't use NGG with [plugin x]", we
 * decided to find a mechanism that would make our plugin immune from such manipulation from other
 * plugins, or at least reduce likelihood of such a thing happening.
 *
 * This is how the mechanism works:
 *
 * When you register a shortcode using Shortcodes::add(), we store a reference to
 * the callback internally, but add the shortcode will actually call one of the internal methods of
 * this class which outputs a placeholder (@see $_privateholder_text) instead of the markup generated
 * by the callback. It's just a simple string and something that a third-party plugin is unlikely to
 * manipulate in any way.
 *
 * We then register a filter for the_content, at high a priority of PHP_INT_MAX as an attempt to make
 * our hook be the last hook to be executed. This hook then substitutes the placeholders with the markup
 * generated by the shortcode's callback that was provided in \Imagely\NGG\Display\Shortcodes::add()

			<h3>Print Lab Integration</h3>
			<p><strong>DO I NEED THIS?</strong> A credit card is needed only if you want to use automated print fulfillment.</p>
			<p><strong>WILL YOU CHARGE ME?</strong> You will not be charged now. Your card will only be charged if someone submits a print lab order on your site. At that point, you will be billed for print and shipping costs from the print lab. You would pay those costs yourself if you worked directly with the lab. We're just automating the process for you.</p>
			<p><strong>IS THIS SECURE?</strong> Assuming you've enabled SSL on your website, then yes. This form sends your card information directly to Stripe, one of the world's leading payment processors. It is stored securely at Stripe, not locally by WordPress or NextGEN Gallery. Note: Without SSL, this form is not 100% secure. You should also enable SSL before receiving payments from your own visitors.</p>
			<p><strong>AGREEMENT: By submitting your card here, you authorise Imagely to bill your card for the cost of print lab orders.</strong></p>

The overall treatment of curves is softer and fuller than in most industrial style sans serif faces.  Terminal strokes are cut on the diagonal which helps to give the face a less mechanical appearance.  Arial is an extremely versatile family of typefaces which can be used with equal success for text setting in reports, presentations, magazines etc, and for display use in newspapers, advertising and promotions.http://www.monotype.com/html/mtname/ms_arial.htmlhttp://www.monotype.com/html/mtname/ms_welcome.htmlNOTIFICATION OF LICENSE AGREEMENT

 * @TODO : Remove all of the following Thickbox specific rules once the Manage Gallery page no longer uses Thickbox.
 * This whole section was added as an annoying hack workaround to the fact that the Manage Gallery page seemingly cannot
 * be forced to correctly enqueue thickbox.css when inside of the attach-to-post controller once the latter was refactored
 * to no longer rely on POPE.

	 * Alias Properties:
	 * gallery_ids/album_ids/tag_ids == container_ids
	 * image_ids/gallery_ids         == entity_ids
	 *
	 * Default Behavior:
	 * - if order_by and order_direction are missing, the default settings
	 *   are used from the "Other Options" page. The exception to this is
	 *   when entity_ids are selected, in which the order is custom unless
	 *   specified.
	 *
	 * How to use:
	 *
	 * To retrieve images from gallery 1 & 3, but exclude images 4 & 6:
	 * [ngg gallery_ids="1,3" exclusions="4,6" display_type="photocrati-nextgen_basic_thumbnails"]
	 *
	 * To retrieve images 1 & 2 from gallery 1:
	 * [ngg gallery_ids="1" image_ids="1,2" display_type="photocrati-nextgen_basic_thumbnails"]
	 *
	 * To retrieve images matching tags "landscapes" and "wedding shoots":
	 * [ngg tag_ids="landscapes,wedding shoots" display_type="photocrati-nextgen_basic_thumbnails"]
	 *
	 * To retrieve galleries from albums 1 & #, but exclude sub-album 1:
	 * [ngg album_ids="1,2" exclusions="a1" display_type="photocrati-nextgen_basic_compact_album"]
	 *
	 * To retrieve galleries from albums 1 & 2, but exclude gallery 1:
	 * [ngg album_ids="1,2" exclusions="1" display_type="photocrati-nextgen_basic_compact_album"]
	 *
	 * To retrieve image 2, 3, and 5 - independent of what container is used
	 * [ngg image_ids="2,3,5" display_type="photocrati-nextgen_basic_thumbnails"]
	 *
	 * To retrieve galleries 3 & 5, custom sorted, in album view
	 * [ngg source="albums" gallery_ids="3,5" display_type="photocrati-nextgen_basic_compact_album"]
	 *
	 * To retrieve recent images, sorted by alt/title text
	 * [ngg source="recent" order_by="alttext" display_type="photocrati-nextgen_basic_thumbnails"]
	 *
	 * To retrieve random image
	 * [ngg source="random" display_type="photocrati-nextgen_basic_thumbnails"]
	 *
	 * To retrieve a single image
	 * [ngg image_ids='8' display_type='photocrati-nextgen_basic_singlepic']
	 *
	 * To retrieve a tag cloud

	 *
	 * - `timeout`: How long should we wait for a response?
	 *    Note: for cURL, a minimum of 1 second applies, as DNS resolution

	 * - `useragent`: Useragent to send to the server
	 *    (string, default: php-requests/$version)
	 * - `follow_redirects`: Should we follow 3xx redirects?
	 *    (boolean, default: true)
	 * - `redirects`: How many times should we redirect before erroring?
	 *    (integer, default: 10)
	 * - `blocking`: Should we block processing on this request?
	 *    (boolean, default: true)
	 * - `filename`: File to stream the body to instead.

	 * - `auth`: Authentication handler or array of user/password details to use

	 *    across transports.)

	 * - `type`: HTTP request type (use \WpOrg\Requests\Requests constants). Same as the `$type`

     *    the appropriate handler installed or when a file type is
     *    unsupported. Can be any text or HTML. Defaults to blank.
     * - `altclass` (string): If a file type is unsupported, the end-user will
     *    see the alt text (above) linked directly to the content. That link
     *    will have this value as its class name. Defaults to blank.
     * - `audio` (string): This is an image that should be used as a
     *    placeholder for audio files before they're loaded (QuickTime-only).
     *    Can be any relative or absolute URL. Defaults to blank.
     * - `bgcolor` (string): The background color for the media, if not
     *    already transparent. Defaults to `#ffffff`.
     * - `height` (integer): The height of the embedded media. Accepts any
     *    numeric pixel value (such as `360`) or `auto`. Defaults to `auto`,
     *    and it is recommended that you use this default.
     * - `loop` (boolean): Do you want the media to loop when it's done?
     *    Defaults to `false`.
     * - `mediaplayer` (string): The location of the included
     *    `mediaplayer.swf` file. This allows for the playback of Flash Video
     *    (`.flv`) files, and is the default handler for non-Odeo MP3's.

     * - `video` (string): This is an image that should be used as a
     *    placeholder for video files before they're loaded (QuickTime-only).
     *    Can be any relative or absolute URL. Defaults to blank.
     * - `width` (integer): The width of the embedded media. Accepts any
     *    numeric pixel value (such as `480`) or `auto`. Defaults to `auto`,
     *    and it is recommended that you use this default.
     * - `widescreen` (boolean): Is the enclosure widescreen or standard?
     *    This applies only to video enclosures, and will automatically resize
     *    the content appropriately.  Defaults to `false`, implying 4:3 mode.
     *
     * Note: Non-widescreen (4:3) mode with `width` and `height` set to `auto`
     * will default to 480x360 video resolution.  Widescreen (16:9) mode with
     * `width` and `height` set to `auto` will default to 480x270 video resolution.
