Surelly, do you have an OpenGL printer or SVG writer ?

About the OpenGL printer:
Setup a framebuffer any resolution you'd like, render whatever you need
to there, then copy the framebuffer to a texture, and save as a high
resolution bitmap. :)

Remove the 'copy the framebuffer to a texture' step since, already back
in the times of OpenGL 1.0 you could read the framebuffer back (albeit
with questionable performance) with glReadPixels(3).

And, of course, it's bugged in a some drivers (for example the bitmap
export in VariCAD is broken at least with IBM chipsets...)
