I suppose, that the total memory consumption does not depend on the
number of \special commands, but only the overall content size of all
\special commands, right?
Is there any way around the internal storage of all \special commands of

When using pm3d with gnuplot, the output consists of many polyons. The
problem is, that the terminal output driver knows nothing about the
number of polygons being plotted. I have to figure out, if there is a
way to get the total number of polygons (do you think, this would help?)
So for every polygon the _filled_polygon() function of the driver is
invoked separately with the coordinates of the four corners.
The output file can look like this:
and so on.
I can send you later a complete output TeX file using my current
