> Just trying to understand the bigger picture. We introduce a new PaintBuffer. Do we want to keep it or it is just a temporary new class? I mean the long term plan is to switch the GraphicsContext to use GLES2 on mobile.

Not sure if that's feasible. The idea is that because canvas is more limited, we have more information to accelerate it. PaintBuffer would accumulate the information, and at some point would choose how to render based on the information it has.
I'm not sure we can do that with standard painting or in the information we have under GraphicsContext.
