[3/5] Add translated rasterization support for RasterBuffer & below
This CL implements the muscle of transformed rasterization. RasterBuffer now
accepts a translation in addition to a scale factor when rasterizing into a
backing.
Arbitrary raster transformation is not planned for near future. Thus only
implementing scale & translate which already helps many common cases.
