GrTessellator (AA): Fix for missing fill artifacts.

Some regions were being incorrectly filled due to setting
connector edges winding to zero *after* merging collinear edges.
This would cause the merge to add the wrong winding value. Putting the
adjust before the call to merge_collinear_edges() fixes the problem.

Also, some pixels were not getting coverage due the inner edge being
+1 winding. Using -2 winding for inner edges ensure the interior
regions are -1 winding, which gives coverage in more cases of
self-intersection. This required flipping the comparisons on the
intruding-vertices workaround.

I've only been running F16 tests in "colorImage" mode.

Expand SkImage::getTextureHandle call

which fills in the entire desc and returns whether the image is texture backed.

AA GrTessellator: fix bevelling of acute angles.

The code to handle acute outer angles in generated geometry was pretty
broken: it did a simple runnning average of consecutive acute vertices,
and didn't handle acute angles between the last and first edges.
Replaced it with something simpler that does proper bevelling for
angles less than 2.5 degrees.

This revealed a bug with thin path segments, exposed by the thinconcavepaths
test. This will be fixed by upcoming changes, but I've also dded a few more
test cases to make it clearer.
