GrPathRenderer. GrAndroidPathRenderer is activated by gyp flag 'skia_android_path_rendering'.
A few changes to get this to work:
- Had to change SkPaint* param to SkStrokeRec& in ConvexPathVertices()
- Had to copy the vertex buffer created by the Android code to GrDrawTarget-generated vertex buffer, and convert float alpha to GrColor for AA paths
