i'm not sure if he wants the same as me,but:

when i wrote my master thesis ( i used pyopengl -)), i needed to make a
lot of screenshots.

and i  also wanted to be able to make eps screenshots. i mean
vector-based eps screenshots.
that means if there is a line on the screen i want it to be described as
a line in the eps file. not as a series of dots. i know that eps is able
to handle vectorial data.
reason:
when printing the master-thesis, all the screenshots look a little ugly,
because the resolution of the monitor is a lot smaller than the
resolution of the printer. with a vector-based image i wouldn't have
that problem.

hope this helps,
