They also move the code into fxjs/ to keep along side the rest of the JS code.

2017-09-22Fix crash when rendering invalid GIFRyan Harrison
The core fix in this CL is a change to how LWZ decompression works, so that when the min code table size and the color palette size are different, color codes after the end of the defined color palette are considered errors. This CL also introduces a bunch of tweaks to the call return path, since there were multiple locations where the GIF decode failing status was being dropped on the floor, so the end widget would have a bitmap with the default colour in it, instead of nothing.
