Oh, that's fine. shm_handle_format (and drm_handle_format, for
non-swrast) gets called to handle events coming in from the server
side. So we will receive WL_SHM_FORMAT_* (not WL_DRM_FORMAT_*) from
the wire, and use that to set enum values which are constant between
SHM and DRM. So I don't see the problem with that.
