Optimization on OffscreenCanvas commit(): allocate canvas backings in shared memory

Project Member Reported by xlai@chromium.org, Sep 29 2016 
In the current implementation of OffscreenCanvas commit(), when the 
Skimage is not texture-backed, the pixels are copied to sharedbitmap.

A possible optimization is to allocate the canvas backings in shared memory right off the beginning, to avoid the copy later.
