I implemented more advanced SVG parsing and manipulation. It's somewhat slower now, I think because I changed the way it skips vertices to save time, but it was necessary to enable slightly more advanced SVG reading (which I have yet to test). All the projections work, though. I also changed my coordinate system. I also broke the bit where it does not draw long lines.
