I'd much prefer an even more radical enhancement: support rich text rendering. That would include word wrapping, but also colors, links, images, fonts, etc. That would make a lot of users happy, I'm sure. I also did a bit of digging into these classes at an earlier stage, and found that it is really doesn't possible to properly support it without some changes quite deep in the rendering code. I found that code too hard to follow to propose a change myself.
