[GRASS-dev] animation missing pnmscale

[Michael Barton]

I thought that of the (main?) goals of doing a TclTk animation replacement
for Xganim was so that we no longer needed motif/lesstif as a GRASS
dependency. While the TclTk animator is nicer looking than xganim, if
pnmscale is required, we just replace one dependency with another one. Maybe
there is another way to do this???
