Screenspace AA tessellated GPU path rendering.
This is an approach to antialiased concave path rendering
on the GPU without using MSAA. It uses GrTessellator to
extract boundary contours from the given path, then
inflates by half a pixel in screen space each direction,
then renders the result with zero alpha on the outer
contour and one alpha on in the inner contour. This
requires two passes through the tessellation code: one
to extract the boundaries, then one to tessellate the
result.
This gives approximately a 3X improvement on the IE
chalkboard demo in non-MSAA mode, a 30-40% improvement
on MotionMark's "Fill Paths", and a ~3X improvement on
MotionMark's "canvas arcTo segments".
It works best for large, simple paths, so there's currently
a limit of 10 verbs in the onCanDrawPath() check. This
dovetails nicely with the distance field path renderer's
support for small, detailed (and cached) paths.

GrTessellator: abstract vertex allocation into caller.
This abstracts all vertex allocation out of GrTessellator via a VertexBuffer interface. This removes all GPU-related calls from GrTessellator.
It also factors vertex drawing into GrTessellatingPathRenderer::drawVertices(), and makes tessellate() (now draw() also responsible for drawing. This means the cache hit case is clearer as an early-out,
and storing into cache is done in draw() as well.
