Thanks.

I haven't reviewed the code yet, but this sounds really fragile and
problematic.  My thought was that TextureCubeMap should fully support
the old usage and the new single Image usage, not try to shoe horn the
new usage onto the old usage.

Yes this will mean some duplicate paths which itself isn't ideal, but
at least it would preserve the original functionality - no user code
should break.
