fail during 2D context rendering.

Reviewed by Kimmo Kinnunen.
ImageData (rect) size and destination offset overflow causes IPC (rect) object
decoder to fail in WebContentProcess, during 2D context rendering which causes
timeout.
Using location and size params in the getPixelBuffer and putPixelBuffer APIs
instead
of rect in order to avoid this issue.
