glfont.cpp has endian problems

[GoogleCodeExporter]

Hi, 

I built heekscad on my Powerbook under OSX. I noticed an endianess problem
with gl fonts. This can be solved with the following patch.

Cheers Torsten

Hi Torsten,
I've built just a few of the cnc modules for Leopard on Intel and Tiger on 
PowerPC.
Could you give us a little info on building all of HeeksCAD for mac? 
Thanks,
Dan

Torsten, I have made the change you suggested, without myself having any
understanding of it.
Let me know if you want to make changes to HeeksCAD yourself and I will add you 
as a
"committer".
Dan Heeks.

Hi Dan,

if "committer" means I can write wiki pages the first would be BuildOnMac. Time
permitting I would like to work on a feature tree but how to do this should be
dicussed first.

Torsten
