OpenGL extension EXT.shared_texture_palette
This module customises the behaviour of the OpenGL.raw.GL.EXT.shared_texture_palette to provide a more Python-friendly API
Overview (from the spec)
EXT_shared_texture_palette defines a shared texture palette which may be used in place of the texture object palettes provided by EXT_paletted_texture. This is useful for rapidly changing a palette common to many textures, rather than having to reload the new palette for each texture. The extension acts as a switch, causing all lookups that would normally be done on the texture's palette to instead use the shared palette.
