[Mesa-dev] [RFC PATCH 06/65] mesa: refuse to update tex parameters when a handle is allocated

[Samuel Pitoiset]

The ARB_bindless_texture spec says:

   "The ARB_bindless_texture spec says: "The error INVALID_OPERATION
    is generated by TexImage*, CopyTexImage*, CompressedTexImage*,
    TexBuffer*, TexParameter*, as well as other functions defined in
    terms of these, if the texture object to be modified is referenced
    by one or more texture or image handles."
