There are standard and nonstandard X extensions that allow some
optimisations (at the cost of portability) "double buffering" is a
common technique to improve animations. Xlib is the lowest (fastest) you
can get; the O'Reily "rainbow series" is the ultimate reference.

Aha, thanks for the answer..
Hmmm... But are the Rainbowseries to get for free on the net or do I need to buy these books(?) ?

ftp://ftp.x.org/contrib/docs/Xbibliography.OReilly.txt contains a list
of the full series, for you volumes 0 and One are the most relevant; the
man pages substitute nicely for volume Two.
