> The PNM image is translated to a PNG.
By what? g.pnmcomp outputs a PPM file.
> This could skip running g.pnmcomp and g.pnmtopng.
g.pnmtopng?
> 2. A 'wxPython driver' could be developed that would dispense with
rendering to files that need to be read.
How would this work?
> 4. The d.* modules simply take some time to render. I'm pretty sure that
this is what takes up the most time in displays, even with displaying to
screen resolution instead of region resolution. Perhaps these could be
sped up. Or perhaps the rendering and compositing could be done in GRASS
in a single step.
In theory, the fastest solution should be to use the cairo driver with
output to X Pixmaps. The d.* modules generate output in video memory, and
may be hardware accelerated. Compositing occurs entirely in video memory,
and may be hardware accelerated. The main unknowns are how hard wxWidgets
makes this, and whether something similar can be achieved on other
platforms.
