With the standardization of properties I'm also trying to get these
expectations better documented, e.g.

https://dri.freedesktop.org/docs/drm/gpu/drm-kms.html#plane-composition-properties

But I think we're not doing a good job yet documenting default
expectations. But the above would be a good place to get that fixed -
this patch here should do that, at least for color keying.
