Add tests for fixed-rate compression extensions
Multiple related extensions are tested by these tests:
- GL_EXT_texture_storage_compression
- GL_EXT_EGL_image_storage_compression
- EGL_EXT_surface_compression
Boilerplate support for these extensions has been added to Mesa but there is no driver implementation just yet. Panfrost support (G310) is currently under review. For EGL_EXT_surface_compression
, only Wayland is supported for now.
