Cleaning up naming of GIF files/classes/variables
Moved everything from core/fxcodec/lgif to core/fxcodec/gif Converted CGifContext -> CFX_GifContext Removed _ptr suffixes from CXF_GifContext Movef fx_gif.* -> cfx_gif.* Renamed structs in cfx_gif.h Renamed members of CFX_GifImage Renamed members of CFX_GifContext Renamed CFX_LZWDecoder -> CFX_LZWDecompressor BUG=pdfium:903 Change-Id: I537e905e935da26832e6bbdc03e0373ed5500bcb Reviewed-on: https://pdfium-review.googlesource.com/14990 Commit-Queue: Ryan Harrison <rharrison@chromium.org> Reviewed-by: dsinclair <dsinclair@chromium.org>
