Yes, I agree that we should use an image cache for this kind of thing,
even though more control over the cache would indeed be a good thing.
Could you send me a complete patch, if possible with doing the caching
from inside TeXmacs and using a safe mechanism for cache names?
Notice also that the -dEPSCrop option of ghostscript does not work
if there is a non trivial offset. For this reason, I just hacked
the code so as to use ImageMagick in that case.

Best, --Joris
