Struct CompatTextureGl 

pub struct CompatTextureGl { /* private fields */ }

Texture/uniform/blend symbols layered on top of CompatGl.

Loading this separately keeps the known-good clear/triangle path alive when older libretro GL proc lookup fails for texture or blending entry points. glActiveTexture is required so callers can restore texture unit 0 explicitly after uploads and draws.
