[PATCH 0/1] MR9486: windowscodecs: correct GIF LZW compression initialization

[Jiajin Cui (＠jin-king1)]

The GIF LZW compression algorithm was incorrectly initializing the code
size to 8 bits regardless of the actual color depth. This caused issues
with images that have fewer colors requiring smaller initial code sizes.
The fix calculates the proper initial code size based on the actual
number of colors in the image, using the formula: minimum code size =
max(2, ceil(log2(color_count))). This ensures proper compression for
images with small color palettes and maintains compatibility with GIF
decoders that expect correct LZW initialization parameters.
