/* ftg.mlabbe -- I renamed this file from glu.h to glutess.h in order to

avoid any future situations where a compile environment puts another glu.h

in the search path ahead of this file.

It is also worth noting that this is a rough rip of the glu tesselation

functionality, and as such, not all of the things declared below actually

exist. It is possible to get link errors, so check if a function exists

before counting on your grand designs.
