18854dcf14 GIF: Handle GIF transparency in the decoder. 
Remove the special case for disposal_method == 1 and handle GIF
transparency by telling the decoder the transparent index.

a4a314f765 GIF: Support transparency in the native decoder. 
Allow the transparency index to be passed to the native decoder.  If not
-1, pixels with this index will be left at their previous value.

This only adds the decoder support and isn't active yet.

480f6819b5 Fix Memory DOS in Icns, Ico and Blp Image Plugins 
Some container plugins that could contain images of other formats,
such as the ICNS format, did not properly check the reported size of
the contained image. These images could cause arbitrariliy large
memory allocations.

This is fixed for all locations where individual *ImageFile classes
are created without going through the usual Image.open method.
