Original change's description:
> Add GM to verify that drawX == (path.addX, drawPath)
> 
> This demonstrates a new kind of hybrid unit test/GM.
> It creates a grid of cells. In each cell, we do two
> renders that are expected to produce the same result.
> For each cell, we render the two results overlaid,
> and highlight any differing pixels in red. Assuming
> there is a diff, the area around the largest diff
> is drawn zoomed in from both images.
> 
> Matching cells are outlined in green, failing cells
> are outlined in red. Triaging this GM just involves
> answering the question: "Are there any red boxes?"
> 
> "Good" example: https://screenshot.googleplex.com/909P3tvS55f.png
> "Bad" example: https://screenshot.googleplex.com/oXBWbEKw5ur.png
> 
> To get more tests to pass, (and fix an assert
> in Ganesh), I've gone ahead and enforced that user
> supplied rects (in drawRect and drawOval) are
> always sorted once they hit the canvas virtuals.
> Currently, drawArc rejects empty ovals, but I added
> the same assert to onDrawArc, if we decide to change
> the strategy there.
