[HOpenGL] GLU.Tessellator crashes

[Balazs Komuves]

Hi,

Indeed, your example code crashes here too, on both OS X 10.5 and Windows XP
(though I would guess that the GLU code is platform-independent).

Since I have tolerance 0, that only happens if you have a duplicated vertex.

I checked the Storable instance for AnnotatedVertex already, and while the
code looks somewhat strange,
it appears to behave correctly.

I will try and look into what happens...
