Unfortunately, many parts of GNOME Shell and Mutter and Clutter
still use the implicit Cogl1 API. As such, it as a transition
between the old and new APIs, it is important to keep the
implicit draw framebuffer updated.
ClutterRootNode does not keep it updated though, and it might
lead to problems when rendering offscreen textures.
Fix that by pushing and popping the root node framebuffer on
pre- and post-draw, respectively.

The ClutterRootNode paint node is theoretically the
top-most node of a paint nodes tree, except that we
are not in the point of having full rendering trees
in Clutter (all rendering performed by paint nodes
is still local and immediate).
When controlling the rendering tree, MetaShapedTexture
may need to paint into an offscreen framebuffer under
some circumstations.
Expose ClutterRootNode so that MetaShapedTexture can
use it to render to offscreen framebuffers.

The multitexture API is not a shortcut for multiple calls
to the single texture API. It is meant to wrap calls to
cogl_framebuffer_draw_multitexture_rectangle(), which
uses the passed texture coordinates at different layers of
the pipeline.

Mutter (and libmutter users) are the only users of this version of
cogl, and will more or less only use the cogl-1.0, cogl-2.0 and cogl
experimental API variants, and having the possibility of having
different API versions of the same API depending on what file includes
it is error prone and confusing. Lets just remove the possibility of
having different versions of the same API.

In cogl use cogl-config.h and in clutter use clutter-build-config.h. We
can't use clutter-config.h in clutter because its already used and
installed.
