SkCanvas interface for drawing a patch.
Added function SkCanvas::drawPatch to the API. This function
receives the patch to draw and the paint.
Added function SkBaseDevice::drawPatch to the API. This function also receives the patch to draw and the paint.
Currently SkGpuDevice and SkBitmapDevice generate the mesh taking into
account the scale factor and call the corresponding device's drawVertices.
