- postscript.c: added some code for frame display, but I'm not happy with it

- postscript.c: moved tedious "... maxfont maxfont ..." into new function
  "boxfont"
- postscript.c: "hcenter" was way off for diagonal text
- postscript.c: "realsize" didn't take into account the effect of rotation and
  returned only the x component in the original coordinate system
- fped.c: feed a dummy argv to gui_init, so that we can parse the arguments
  before deciding whether to bring up the GUI
- fped.c: don't bring up Gtk+ if we're not going to use it
