I'm trying to do something very simple: I need some parallelograms in my program. These are attached to other objects, all of which are UIViews. It's important that I be able to animate these, since the objects they are attached to can also be animated.

I've figured out how to use the transform in UIView/CALayer to do this, but the problem is that these sheared UIViews don't look very nice: there is no anti-aliasing of the edges.

Is there some other way to do this? I would like to use UIViews, since I also use them for user interaction and animation is so much easier than drawing by hand. I don't want to use OpenGL for this.
