- Dotted and dashed ellipses.
-
- In troff mode, dotted and dashed splines.
-
- Make DELIMITED have type lstr; this would allow us to give better
- error messages for problems within the body of for and if constructs.
-
- In troff mode without -x, fake \D't' with .ps commands.
-
- Perhaps an option to set command char.
-
- Add an output class for dumb line printers. It wouldn't be pretty but
- it would be better than nothing. Integrate it with texinfo. Useful
- for groff -Tascii as well.
-
- Option to allow better positioning of arrowheads on arcs.
-
- Perhaps add PostScript output mode.
-
- Change the interface to the output class so that output devices have
- the opportunity to handle arrowheads themselves.
-
- Consider whether the line thickness should scale.
-
- Consider whether the test in a for loop should be fuzzy (as it
- apparently is in grap).
-
- Possibly change fillval so that zero is black.
-
- Provide a way of getting text blocks (positioned with `.in' rather
- than \h), into pic. Should be possible to use block of diverted text
- in pic. Possibly something similar to T{ and T} in tbl.
-
- Option to provide macro backtraces.
-
- Have a path that is searched by `copy' statement. Set by environment
- variable or command line option.
