Reason for revert:
This is leaking memory:

Original issue's description:
> Picture Recording: fix the performance bottleneck in SkDeferredCanvas::isFullFrame
>
> blink skips all pending commands during picture recording if it is drawing an opaque full-frame
> geometry or image. This may improve performance for some edge cases. To recognize an opaque
> full-frame drawing should be cheap enough. Otherwise, the overhead will offset the improvement.
> Unfortunately, data from perf for content_shell on Nexus7 shows that SkDeferredCanvas::isFullFrame
> is far from cheap. Table below shows that how much isFullFrame() costs in the whole render process.
>
> benchmark percentage
> my local benchmark(draw 1000 sprites) 4.1%
> speedReading 2.8%
> FishIETank(1000 fishes) 1.5%
> GUIMark3 Bitmap 2.0%
>
> By contrast, real recording (SkGPipeCanvas::drawBitmapRectToRect) and real rasterization
> (GrDrawTarget::drawRect) cost ~4% and ~6% in the whole render process respectively. Apparently,
> SkDeferredCanvas::isFullFrame() is nontrivial.
>
> getDeviceSize() is the main contributor to this hotspot. The change simply save the canvasSize and
> reuse it among drawings if it is not a fresh frame. This change cut off ~65% (or improved ~2 times)
> of isFullFrame().

> telemetry smoothness canvas_tough_test didn't show obvious improvement or regression.
