[PATCH v3 1/2] wined3d: convert 3D DXTn textures
Connor McAdams
conmanx360 at gmail.com
Sat Jun 23 17:21:54 CDT 2018
This adds decompression functions for DXT1, DXT3, and DXT5 formats,
which covers all the possible DXT formats. These are used for
decompressing DXTn volume textures, and converting them to b8g8r8a8.
This patch also makes sure only 3D DXTn textures are uploaded by
performing a check in the wined3d_texture_upload_data function.
