it doesn't seem to work on my box. no matter, what shader i load, the
texture looks the same. when i click on one of the shader loaders, i get
the following messages:
[pix_texture]: using mode 0: TEXTURE_2D
linking: link 5.60519e-45 4.2039e-45

no change in the picture whatsoever.
also the ID number is out of the range in order to be represented
i remember there was a discussion once about this on the gem-dev list.
is there a fix for that?
i am on ubuntu hardy with an nvidia Quadro NVS 140M and i very much
hoped, that i have now opengl 2.x. glxinfo:
OpenGL version string: 2.1.2 NVIDIA 169.12
do you think, shader stuff is supposed to work on my box? if so, what
can i do to make it work?
