I used qt-copy and kdelibs from trunk. They worked, just that later when 
running cmake in kdebase dir, I had to add  -DKDE4_IGNORE_DONTPORT=ON  to 
cmake's commandline.

I non-recursively (with svn's -N flag) checked out kdebase, then 
kdebase/workspace and kdebase/workspace/kwin, then  svn switched to kwin 
branch. Only thing I had to change was commenting out other directories in 
CMakeLists.txt in kdebase and kdebase/workspace

I added  #define HAVE_XDAMAGE  to config.h, after that everything worked well.

So I managed to compile and start kwin (on top of Xgl). It worked, but it 
usually froze as soon as I tried to do something with it such as changing 
active window. KWin's window menu (the one you get after RMB on window's 
titlebar) also didn't work correctly, it opened, but I couldn't click on any 
of the menu items. Moving windows worked though and showed the new 
effects ;-)

I think the first think that needs to be done for OpenGL support is writing 
code to initialize OpenGL. Does anyone have any experience with that or does 
anyone know if we can use QGL? If not, maybe we could use compiz's 
initialization code, at least for now?
