VDrift 12-26-07 Mac OS X Release don´t start

[abs1nth]

forget my last post, that was completely wrong, but thanks to accesses to a affected machine, i figured it out ;-)

glUniform1f() etc is only available in opengl 2.0, previously the same function was called glUniform1fARB(), so when opengl 2.0 is not available, we get the crashes.

please apply (something like) the patch as i'm away from home.

also, i noted if you got an old preferences file which has no entry for shaders, the default is ON - this should probably changed.

patch:
