[AFAIR, this didn't go via r-devel, so people here won't have seen it 

I suppose I should put it somewhere for others to play with. It should 
be possible to reduce the number of colour layers and get down to  the 
50 K or so, but it is quite fiddly. I found that if you put inkscape in 
"outline mode", then you can manipulate the Bezier curves directly and 
get rid of the artifacts from the bitmap tracing. Currently, it has 
about 64 paths of about 60 control points each, so it might be a better 
strategy to start over with a coarser trace.

Mmm, I'm changing jobs on Monday and I expect to be out cold for a 
while, switching computer platform and getting up to speed in general. 
Any chance of a couple of screenshots?

This sounds a bit far-reaching. The "-g Tk" route is a bit of a kludge 
already, so everything is in for a review and I'd rather not build 
things on top of a crumbling foundation.

You might be able to do something with environment variables and 
.Rprofile files instead. (I was about to suggest 'R -e something' but 
Rcmdr refuses to start in a non-interactive session).
