Might need some more test cases here with different matrix types.

+        canvas->drawPatch(coons, paint);
 
         //draw control points
         SkPoint bottom[4];
         coons.getBottomPoints(bottom);
         SkPoint top[4];
         coons.getTopPoints(top);
         SkPoint left[4];
         coons.getLeftPoints(left);
         SkPoint right[4];
         coons.getRightPoints(right);
