The easiest solution is to use two graphics and strategic grouping to take care of clipping:
1 Rectangle graphic, grouped to clip off the top or bottom half
1 RoundRect graphic, grouped to clip off the top or bottom half
Then group these two groups and script a behavior to handle resizeControl messages and provide setProp handlers that control the inner groups.
Play around with gradients and graphic effects to finish off.

At least that's how I've done it ;-)
