Coordinated Graphics: LayerTreeRenderer manages the surface of UpdateAtlas.

Patch by Huang Dongsung <luxtella@company100.net> on 2013-01-30
Reviewed by Benjamin Poulain.

Currently, CoordinatedLayerTreeHostProxy manages the surface of UpdateAtlas, but
all other resources are managed by LayerTreeRenderer. This patch matches the
surface of UpdateAtlas to other resources.
