I'm not sure where this is documented (not my area of expertise), but 
IMHO this is why good communication is important: if you asked mesa-dev 
or #dri-devel "How do I check if DRI2 is enabled?" someone would have 
gladly taken the five minutes and pointed you to the right solution in 
the first place.  We really are here to help...if you have questions, 
feel free to ask.

You're absolutely right that KWin has to work out of the box (as well as 
Compiz and GNOME Shell).  I'd been testing it on the Intel drivers, but 
missed this...sorry.  We have a lot going on and sometimes things slip. 
  I'll talk to our QA team about testing KWin before releases.

Please do let us know about any issues you come across. (If you can work 
around them, you can report them...)  Even just a ping saying "Someone 
told me KWin was broken on <platform/version>" is helpful.  We have the 
hardware and can always try to reproduce the problem, even if you aren't 
able to.

Also, FWIW, GLSL 1.20 (and GLSL ES) should work fine in 7.9 or later. 
If it doesn't, we'd really like to know.

Thanks for all your work on KWin and KDE.
