OnPoint
So now you've got a grid layout with the blocks already on-point, and the setting triangles already set up.
If you try to insert a 9 patch into the triangle, for instance, it will only put half in, and you can rotate that design within the triangle.
And if that didn't/doesn't make sense, let me now and I can try it again. ;) ;)
