Okay - Paintcode to the rescue. I made my art in Illustrator, and I can
support up to 45 values @ the moment (each segment an 8ยบ rotation). I
if/else the hell out of whether or not a line gets stroked based on the
number of ticks. At least my artwork for the dial looks good now. Thanks
for that suggestion. If I ever need more than 45 values, I'll probably need
to revisit this solution, but I should be okay.
