[GRASS5] i.composite problems verified

[Andreas Lange]

Hi Glynn and Eric,

i vote for removing the paint drivers. But i noticed that some functions
are implemented in the paint driver that are currently missing in the
ps.map program, e. g. point, setpat, defpat. And i think that site and
raster legends (slegend, rlegend) are missing (compare vlegend
command!). 

One general consideration should be that creating printed maps and
creating maps for screen viewing/world wide web is very different. So a
single architecture for display and hardcopy output has drawbacks. 

I currently have some problems with ps.map ps output and ps2pdf on linux
(on cygwin it works!). Will work on this later on.

cu,

Andreas
