This adds a hook called COGL_SNIPPET_HOOK_TEXTURE_COORD_TRANSFORM. This can be used to alter the application of the layer user matrix to a texture coordinate or it can bypass it altogether. This is the first per-layer hook that affects the vertex shader state so the patch includes the boilerplate needed to get that to work. Reviewed-by: Robert Bragg <robert@linux.intel.com>
