smooth drawing with jit.lcd

hello jitterers,

i am trying to make a drawing program with jit.lcd. to fake anti-aliasing, i'm actually just moving a picture of a dot around that has faded edges and using the penmodes to blend. it looks great, except that if i move the "brush" too fast, i get a line of dots. i thought i could use the line object to fill in the gaps, but even with the fastest sample interval, and long ramp times, it still skips a lot of numbers. i also switched to using mousestate instead of getting mouse info from the window because it seems able to sample the mouse position faster, but neither helped.

any suggestions on how to make the line continuous?

or has anyone made a good drawing patcher i could take a look at?

thanks,
aaron
