Try and create some basic icons using CSS instead of bitmaps? We could inject the necessary markup with JS. These would be high res and scalable. Most core icons are very simple right now:

+, -, x (delete), arrow up/down/left/right, sort grippy bars

Ideally, we could use this for radiobuttons and checkboxes too. Since Doug's the master, maybe he can weigh in on whether this is feasible.
