[Re: [GRASS-dev] GL + PPM + nviz]

Listers,

The OpenGL portion of the nviz high-resolution PPM export does not work
as intended for most individuals at present:

Then I guess the best that can be done is to ensure that
GRASS_NO_GLX_PIXMAPS and GRASS_NO_GLX_PBUFFERS are widely documented.
Would it be best to set them for now until conditions improve to
minimize user impact?

I suggest putting that question to the mailing list(s).

If they are disabled by default, the variable names should probably
have the "NO_" removed, and accept 0/1 values, e.g.

GRASS_GLX_PIXMAPS=0 # force off
GRASS_GLX_PIXMAPS=1 # force on
# anything else = default = off for now, on if the feature eventually
# becomes usable on the majority of systems

I suggest that the default for 6.2 should be "off" (ship a working
product), for 6.3 it should be "on" (it IS a dev version...). If "off"
for 6.3 I think this will never be fixed.

and testing for "0" || "FALSE" and "1" || "TRUE" is nice,
