glx tfp: make clutter_glx_texture_pixmap_update_area cheap
This changes clutter_glx_texture_pixmap_update_area so it defers the call to glXBindTexImageEXT until our pre "paint" signal handler which makes clutter_glx_texture_pixmap_update_area cheap to call. The hope is that mutter can switch to reporting raw damage updates to ClutterGLXTexturePixmap and we can use these to queue clipped redraws.
