sample GIF which crashes Mono
Description of Problem: GDI+ is unable to load GIF images which contain layers which have an offset other than 0,0
Steps to reproduce the problem:
1. load the attached animated GIF as a resource
fails to load
How often does this happen?
The problem can be worked around by editing the GIF image so that all layers have the offset of 0,0. Because of poor error checking in Image.cs, this problem took a very long time to hunt down.
Component should be libgdiplus rather than Windows.Forms, but I can't seem to be able to edit this bug, for some reason.
