I wrote the gtkglarea wrapper based on what was in cvs back in july. It
will compile against the version of gtkglarea in CVS, which has the
swapbuffers function marked as deprecated, so I used swap_buffers. The
gtkglarea guy has not released a new version since then, which is why the
current python gtkglarea wrapper fails.
I think there is a snapshot of the newer gtkglarea available on the
author's web site which should work.
