Bug 948765 - Port CopyableCanvasLayer to Moz2D. r=nical

Browse Source 
This patch deprecates the UpdateSurface and PaintWithOpacity methods in the
CCL class. To do this, many other changes were made in the process.

BasicImplData::Paint was deprecated, and its mOperator was ported to Moz2D.
This caused changes in several *Layer subclasses.

GLScreenBuffer::Readback was deprecated.

I want to change the usages of the (now) deprecated functions, so that they
use the new Moz2D ones: CanvasClient::Update has been updated, but the big
one (BasicLayerManager::PaintSelfOrChildren) will have to be its own
project.
