Robert Bragg 2762e6d9b9 [texture] push/pop draw buffer when painting actors to a texture
When updating the FBO for a source actor (to support
clutter_texture_new_from_actor()) we used to simply set an offscreen draw
buffer to be current, paint the source actor and then explicitly set the
window to be current again.  This precluded chaining texture_new_from_actor
though because updating another FBO associated with a source actor would end
up restoring the window as the current buffer instead of the previous
offscreen buffer.  Now that we use Cogl's draw buffer stack; chaining
clutter_texture_new_from_actor() should be possible.
