  Add experimental feature to control image animation play/pause state

Reviewed by Said Abou-Hallawa.

This patch adds a new experimental feature that enables control of image
animation play / pause state. Animations can be paused or played
globally and individually.

Note these new controls are exposed only via Internals (for testing
purposes) with this patch. There will be follow-up patches to expose
these controls via user interface.

Patch authored by Josh Hoffman with slight modifications by me (Tyler
Wilcock).
