[gl2ps] Tutorial for implementing new backend driver?

Hi, there!

I am thinking about implementing a new backend driver for gl2ps. It
would be "pgf", a graphics layer for LaTeX (\usepackage{pgf}), in order
to enhance graphics-support for TeX. The reason is that I had some
troubles with my pdf-snapshots of openGL scenes: Sometimes hairlines
appeared in an image (posted this long ago, but there had not been a
solution yet).

The reason for this message is that the gl2ps webpage says that
implementing new backend drivers should be easy. Before I start working
through the sourcecode myself, could somebody maybe just give me a very
brief guideline how to do this? (Just a few lines like "1. provide
function void pgfbackenddriver()... 2. register function
pgfbackenddriver() as a new backend driver in function init(), 3. write
hooks for gl-feedbacks like this: ...). It will definitely save overall
time for developing.

Thanks,

	Fabian
