Fixed demo

Seems like texture dimensions are the problem. Some of you have an older version of OpenGL(1.1 or so) so it doesn't support textures ! power of 2.
Maybe that's also causing the slowdown on certain computers [smile].

Final testing on my mums computer later today, then I will upload(this fucking school won't let me create/upload .zip files anyway HAXXOR).

EDIT: Fixed Demo

Laterz,
