Something in Gallium is probably deciding that GL_DEPTH_COMPONENT is

Hmmm, I'm not sure what would be preventing cube textures in gallium or the
state tracker.
Something in Mesa is doing it,
texobj.c:_mesa_test_texobj_completeness
has a check for CUBE + DEPTH_COMPONENT on line 674.
How should we remove that with a GL3 version check?
My first inclination is:
if (ctx->VersionMajor < 3 && t->Image[face][i]->_BaseFormat ==
GL_DEPTH_COMPONENT) {
So we basically assume that depth cubes work if all the other GL3
features are available.
The other approach would be to define a (hidden) extension flag
indicating support for depth cubes which GL3 would depend on.
I don't have a strong preference.
