So, given that the set of formats is defined unconditionally in
gl-renderer, this would break compilation with --disable-drm-backend.
The options that come to mind are either: using wl_shm enums for these
formats, shipping a local copy of drm_fourcc.h, or mandating the DRM
backend for dmabuf. Of those, I'd prefer the first, I think.

I did merge your YUYV patch, though: thanks!

Cheers,
Daniel
