 * The RasterMaskHelper helps generate masks using the software rendering

 *
 *   RasterMaskHelper helper(pixmapstorage);
 *   helper.init(...);
 *   helper.drawShape(...);
 *
 * The result of this process will be the mask rendered in the Pixmap,
 * at the upper left hand corner of the bounds.
 *
 * TODO: this could be extended to support clip masks, similar to GrSWMaskHelper.
