Comment (by adamsilverstein):

 r53751 lays the foundation for multi-mime support; I am leaving the ticket
 open for several other patches (which are mostly complete already) to:
 * Add control over mime type support in `add_image_size` (also reviewing
 other core media functions)
 * Add the WebP shim (which uses the jpeg instead) for non-supporting
 browsers
 * Add plugin integration points
 * Add additional mime type output during media edit flow
 * Add new media meta data in REST API media endpoint
