--blur and --saturate don't play well with --rotate

I noticed that if --shape is set to triangle and you use --rotate, it kinda breaks --blur and --saturate. Try it and see what I'm talking about. What I think is happening is the matte (/tmp/polyfy1.png) is getting rotated properly but isn't getting moved to where the border is being drawn. Unfortunately, I'm not quite sure how to fix this.

Yeah. This is because the triangles height is different from its side length so the matte height != matte length (unlike with square, diamond, circle). Haven't had time to go back and figure out how to fix it, but it's on my todo list.
