685634 - Review gif animation polling tests

Status: NEW

(Core :: Graphics: ImageLib, defect, P5)

Description

[Scott Johnson (:jwir3)]

For bug 666446 8 tests, along with a test framework, were added to the imagelib test suite. They all poll for animated images in different conditions. However, it would be more elegant if we could register an onStopFrame handler, and verify each frame individually, rather than simply polling for the final frame.

For some images, such as background images, it's unclear whether we can get access to an imgIRequest object from javascript. We need to investigate whether this can be done, and implement it, if possible.
