pointtype symbols

Symbols used for the first eight numerical point types are consistent across all terminals to the extent possible. Some terminals provide a larger set of symbols (PostScript provides 75!). In general a terminal providing N symbols will re-use these cyclically. For example the cairo terminals provide 15 distinct symbols; after that the symbols repeat in order, so the symbol used for "pointtype 16" is the same as that for "pointtype 1" although it may use a different color. Use the test command to see the symbol types.
