1In troff mode, dotted and dashed splines. 2 3Make DELIMITED have type lstr; this would allow us to give better 4error messages for problems within the body of for and if constructs. 5 6In troff mode without -x, fake \D't' with .ps commands. 7 8Perhaps an option to set command char. 9 10Add an output class for dumb line printers. It wouldn't be pretty but 11it would be better than nothing. Integrate it with texinfo. Useful 12for groff -Tascii as well. 13 14Option to allow better positioning of arrowheads on arcs. 15 16Perhaps add PostScript output mode. 17 18Change the interface to the output class so that output devices have 19the opportunity to handle arrowheads themselves. 20 21Consider whether the line thickness should scale. 22 23Consider whether the test in a for loop should be fuzzy (as it 24apparently is in grap). 25 26Possibly change fillval so that zero is black. 27 28Provide a way of getting text blocks (positioned with `.in' rather 29than \h), into pic. Should be possible to use block of diverted text 30in pic. Possibly something similar to T{ and T} in tbl. 31 32Option to provide macro backtraces. 33 34Have a path that is searched by `copy' statement. Set by environment 35variable or command line option. 36
