DisplayOutput/OpenGL/glx.cpp:538:28: warning: ‘KeySym XKeycodeToKeysym(Display*, KeyCode, int)’ is deprecated

What steps will reproduce the problem?
1. svn checkout http://electricsheep.googlecode.com/svn/trunk/ 
electricsheep-read-only
2. autogen.sh; ./configure; make
3. observe make during glx.cpp compiling

What is the expected output? What do you see instead?

I am not a C++ programmer, mostly, but I was poring over some documentation and 
tried to hash together my own solution, which, as far as I know, is eliminating 
the deprecation warning, however, I am still having trouble with the client 
after it downloads sheep, so this mock patch may not even be fixing the real 
issue as far as I know (diff: orig< >new):

# diff ./DisplayOutput/OpenGL/glx.cpp 
/usr/src/electricsheep-dev/client_generic/DisplayOutput/OpenGL/glx.cpp
