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?"

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.

When path features are exactly a pixel wide, the extruded inner edges
can become collinear and then be removed, since their winding is
zero. We need these edges to be preserved through triangulation,
otherwise opaque portions of the geometry can become transparent.
Since the simplify() pass can handle zero-winding edges just fine, the
the fix is to simply not remove them.
In addition, this changes refactors out disconnect() from all the calls
to remove_edge_above()/remove_edge_below(). It also renames the remaining
function erase_edge() (since it's now unconditional).
Add a new test to a new "thinconcavepaths" GM.
