Neil Roberts 3ebe48105d cogl-atlas-texture: Try to do texture blits using an FBO 
When reorganizing the textures, we can avoid downloading the entire
texture data if we bind the source texture in a framebuffer object and
copy the destination using glCopyTexSubImage2D. This is also
implemented using a much faster path in Mesa.

Currently it is calling the GL framebuffer API directly but ideally it
would use the Cogl offscreen API. However there is no way to tell Cogl
not to create a stencil renderbuffer which seems like a waste in this
situation.

If FBOs are not available it will fallback to reading back the entire
texture data as before.
