Hi all,
I had a SEGV when trying to run teeworlds (client) on a linux box without
OpenGL support. This is due to a bad check of gfx_init() return code.
Here's a fix:

- if(!gfx_init())

return;

Here's the backtrace for anyone interested:
[496f74ee][gfx]: unable to set video mode: Couldn't find matching GLX visual
[496f74ee][gfx]: out of ideas. failed to init graphics
