Steps to reproduce:

After imagelib has undergone refactoring that could improve its testability, create a test for corner cases such as bug 890743 - probably not tests that depend on time factors and the output of 3 different threads (decode thread, main thread and compositing thread), but on functional output that depends on properties of an image.

Specifically, what we need to test bug 890743 better is the ability to unit test the animation functionality in imagelib. Integration tests are likely to be very challenging for that feature since there is so much in the environment that can affect the outcome. (Bug 890743 comment 25 has some discussion.)
