Best practice for creating a resizable HUD-style widget stack background?

[Nonsanity]

You can probably get away with drag-to-resize a round-cornered window by
changing to a square-cornered window when they start to drag, perhaps a
transparent one. The round-cornered graphics can still be visible and
expanding live. When they let go of the drag, re-calculate the
round-cornered mask from the now-resized graphics and re-apply.

(Hmmm, there sure were a lot of dashed-words in there...)
