Benchmark tiling now better reflects how it is done in Chrome.

Benchmark tiling now better reflects how it is done in Chrome.

Namely, the tile backing stores are all the same size.

Currently, what has been written for the accelerated canvas tiling path has to
first move the tile down and then flip it (see updateTextRect in
chromium/src/third_party/WebKit/Source/WebCore/platform/graphics/chromium/FrameBufferSkPictureCanvasLayerTextureUpdater.cpp).
I haven't implemented this yet though, should I?

I think it is not important to capture that in the benchmark since it won't
impact performance, unless you tell us we have to flip in a temp buffer.
