* Init is the default method responsible for rendering
* a pixel-ratio-aware images.
*
* This method is used to select the images that
* should display retina-size images on high pixel ratio
* devices. Dense defaults to the init method if no
* method is specified.
*
* When attached to an image, the correct image variation is
* selected based on the device's pixel ratio. If the image element
* defines <code>data-{ratio}x</code> attributes (e.g. data-1x, data-2x, data-3x),
* the most appropriate of those is selected.
*
* If no data-ratio attributes are defined, the retina image is
* constructed from the <code>src</code> attribute.
* The searched high pixel ratio images follows
* a <code>{imageName}_{ratio}x.{ext}</code> naming convention.
* For an image found in /path/to/images/image.jpg, the 2x retina
* image would be looked from /path/to/images/image_2x.jpg.
*
* When image is constructed from the src, the image existance is
* verified using HTTP HEAD request, if <code>ping</code> option is
* <code>true</code>. The check makes sure no HTTP error code is returned,
* and that the received content-type is of an image. Vector image formats,
* like svg, are skipped based on the file extension.
*
* This method can also be used to load image in semi-lazy fashion,
* and avoid larger extra HTTP requests due to retina replacements.
* The data-1x attribute can be used to supstitute the src, making
* sure the browser doesn't try to download the normal image variation
* before the JavaScript driven behaviour kicks in.
*
* Some classes are added to the selected elements while Dense is processing
* the document. These classes include <code>dense-image</code>, <code>dense-loading</code>
* and <code>dense-ready</code>. These classes can be used to style the images,
* or hide them while they are being loaded.

* @param {String} [options.glue=_] String that glues the retina "nx" suffix to the image. This option can be used to change the naming convention between the two commonly used practices, <code>image@2x.jpg</code> and <code>image_2x.jpg</code>

- CSS: CSS stack that works independently from the rest of Velocity.
- animate(): Core animation method that iterates over the targeted elements and queues the incoming call onto each element individually.
- Pre-Queueing: Prepare the element for animation by instantiating its data cache and processing the call's options.
- Queueing: The logic that runs once the call has reached its point of execution in the element's $.queue() stack.
Most logic is placed here to avoid risking it becoming stale (if the element's properties have changed).
- Pushing: Consolidation of the tween data followed by its push onto the global in-progress calls container.
- tick(): The single requestAnimationFrame loop responsible for tweening all in-progress calls.
- completeCall(): Handles the cleanup process for each Velocity call.
