- Bind CanvasPixelArray wrappers to the backing store directly without
  the use of an interceptor.

Landed upstream by Dimitri as http://trac.webkit.org/changeset/46495

This is the minimal change which needs to go into the V8 bindings to start using
the pixel array data in V8. The pixel array support in V8 is being added with
this change list: http://codereview.chromium.org/159263

I am aware that there are more custom functions which can be removed eventually,
but I left them all in for now to be able to switch back to the original code
quickly.

Thanks for your feedback,

File bindings/v8/V8DOMWrapper.cpp (right):

http://codereview.chromium.org/160259/diff/1/2#newcode295
Line 295:
//descriptor->InstanceTemplate()->SetIndexedPropertyHandler(USE_INDEXED_PROPERTY_GETTER(CanvasPixelArray),
USE_INDEXED_PROPERTY_SETTER(CanvasPixelArray));
This will be removed before commit, but it helps being here to debug for now.

http://codereview.chromium.org/160259/diff/1/2#newcode565
Line 565: result->SetElementsToPixelData(pixels->data()->data(),
pixels->length());
I will change the API call in V8 to SetIndexedPropertiesToPixelData to align the
naming with the rest of the API.
