Replying to [comment:6 martinl]:
> I was thinking about something similar, btw, is there any display driver
in GRASS which already doing down-sampling? Thanks for any hint.
The PNG driver resamples each row and stores it directly in the image.
The PS driver writes the data to the PostScript file as-is (after
conversion to hex). This can potentially result in huge files, but it
doesn't affect memory requirements (PostScript "streams" image data into
the frame-buffer from the input file; it doesn't store it in memory prior
to rendering).
