[Gmsh] some small bugs on gmsh 2.2.0

[Dr.-Ing. Ingo D. Rullhusen]

Hello,

on my Core-Duo with openSUSE 10.2/64bit it seems to work, but on my 
Pentium III with openSUSE 10.3/32bit there are some problems:

1) The direct rendering gives a misplacing of the xyz labels of the 
tripod, they are placed in the middle of the right side and doubled; 
lines and dots are too thin, with indirect rendering it works.

2) I must compile gmsh with -O0 option otherwise it locks immediate on 
3D meshing no matter what settings.

Thanks
Ingo
