Flow/wrap text into an irregular shape

It has just occurred to me that scrolling within a shape will be very
cpu-active, as the visible text would be reflowing with each line advance.
 This probably isn't worth the cpu hogging it would need, and probably
wouldn't scroll very smoothly either.

Maybe instead of wrapping the text, I could use the triangle as a mask,
showing only the inside text.  To read or edit it, click and it becomes a
normal field again.  Perhaps not as nifty looking, but definitely easier to
achieve using graphic effects and/or ink blending.
