rewrite of code

I've been rewriting the code that runs in the background to make the plotter work. This isn't evident at all to someone watching it run but it leaves more room for me to make the main program bigger.
I ported the "all" program over to the new system. This draws four pictures in sequence for a long display of the plotter. The four pictures are triangle, fourballo, cesaro4 and dragon. Here are pictures of what it drew. I used a very fine point chisel tip marker. I think I like thicker tip bullet tip markers better.

triangle

fourballo

cesaro4

dragon

If anyone is interested in the actual code leave me a comment.
