further documentation:
cgf_sfx_glass.cpp can be compiled with ordinary c compilers as
well - just change the extension from .cpp to .c
to install breakable glass in the ActionQuake2 1.51 code base,
do the following:
@ file a_game.h
+ modify
#define ACTION_VERSION "1.51"
to something that tells users breakable glass is supported
@ file a_team.c
+ add #include "cgf_sfx_glass.h"
