ImageSourceCG.cpp uses a WinIE-like >50 ms minimum cutoff for GIF frame durations. But the code in image-decoders/gif/GIFImageReader.cpp (used by Cairo, QT) uses =10 ms.
Patch to make the non-CG ImageSources work like ImageSourceCG coming shortly.

This makes the various ImageSource*.cpp files look closer to ImageSourceCG.cpp, including using the same threshold value. It also makes GIFImageReader.cpp closer to the original Mozilla source.
