quakeforge-old/common/cl_main.c
Joseph Carter bb5623aa9e input.h is gone - was empty anyway. vid_x11.c now is responsible for init 
of the input routines it can use.  All vid targets should do this for the
input method they should use.  While this is essentially hardcoding, it's
kinda necessary for now.  Once we have everything working and tested we
can work on an interdependency scheme so X input methods only work with X
output methods, etc...
