gl-renderer: Ignore INVALID modifier
If the user has passed an INVALID modifier, it's because there is no applicable modifier, and the buffer layout should be determined by a magic side-channel call (e.g. bo_get_tiling). If the modifier is INVALID, don't try to pass it through to EGL, but just drop it. On the other hand, if a modifier _is_ explicitly specified and we don't have the modifiers extension, then refuse to import the buffer. Signed-off-by: Daniel Stone <daniels@collabora.com>
