a5ebd143d6 gif2webp: Bgcolor fix for a special case 
When transparent color index and background color index are same,
we should set background color to 0x00ffffff (transparent).

For this, we delay setting the background color until we have read the
first frame.

this would require a PRIuS or similar macro for proper platform
compatibility (Visual Studio for instance would be variants of %lu)
