Projects, in no particular order:

- revise border command to use keywords
- clean up includes at the top of all files (string etc)
- put minor tics into demo file

longer term

- break it into three layers:
  : low lever graphics  (some of term.c)
  : plotting code, reading the setshow.h global variables
  : front end, with parsing, etc
  basically, gplotlib is layer 2, and the traditional gnuplot is
  a client of gplotlib
