821571 - Add some sort of temporal media fragment support for animated images

Status: NEW

(Core :: Graphics: ImageLib, defect)

Description

[Seth Fowler [:seth] [:s2h]]

It would be convenient for our UI code if we were able to use temporal media fragments with images. At a minimum, it's desirable to be able to select a specific frame (probably most frequently the first) - this would come in handy for disabling animation in situations like bug 821011. One could imagine using a special media fragment dimension like #frame for this, or piggbybacking on #id.

We could also consider supporting the #t dimension for images. This would be more complex as the units are time and it would require us to be able to select a set of frames rather than just one. It's not a good fit for our immediate needs, so it seems to me like we should leave #t support out of this bug, but it might be that people would have a use for this.
