Re: [ft] Tesselationg Fonts with gluTesselator

[Bertrand Coconnier]

Hello Nathan,

Both winding rules (GLU_TESS_WINDING_ODD and GLU_TESS_WINDING_NONZERO) 
work ok for me : they give the same result.

What I understand from the docs is that if you use 
FT_Outline_Decompose() the scan-converter will always parse the outline 
using the non-zero winding rule, whatever is the actual winding rule of 
your font.

But may be I am wrong ?
