That's a well-known restriction. I recently saw that Simon Urbanek et al at
the U of Augsburg added a 'gdd' graphics device based on libgd that does away
with the X11 server restriction. Haven't heard of any real tests with
it. I'll probably see Simon (who's now at Bell Labs or whatever they call it
these days) at a conference this weekend so I can ask :)
