[Kwintv] OpenGL view mode and a new threading solution

[Dirk Ziegelmeier]

Hello,

I've rewritten the OpenGL view mode code. Anybody with hardware OpenGL 
acceleration, please try it (the latest ATI drivers OOPS on my SuSE 
9.1 :-((( ). However, it is still unstable and may make the program HANG at 
shutdown. But if it works well, I'll try to find a solution for it.

Another solution for the threading problems in kdetv may be a "XInitThreads()" 
call in main.cpp. It works fine, only OpenGL freezes at widget creation. 
Also, I found many places in the net where problems with this call are 
described; even Qt does not call it by default. Does anyone have experience 
with it?
