Basically what I'm trying to do is allow people to write with a wacom tablet and dynamically record videos of them doing so, but I want it to resemble (as closely as possible) actual handwriting. Drawing (using default lineto) with jit.lcd (especially when the size of the lcd is increased) is jaggy as all get out. So I managed to enable drawing using paintoval but the difficulty now is creating continuous "lines". You'll notice if you move the mouse quickly it leaves big gaps - no good. I encountered the same problem with a simple processing sketch. Maybe I am going about this completely wrong, not sure.
