Yep, Darren got "draw_markers" properly implemented for backend PS.
This function is much better in time and space; I believe only *Agg
and PS implement it, but it could be ported over to SVG fairly easily
by modifying the PS implementation.

Agg does this for draw_lines -- it drops points in the path that are
less one pixel away from the previous point.
