given your changes to the twin source base I consider this as joke - to be 
honest. To come here with quality control, while you don't have any for you 
own. That's a very bad joke and reads to me like "I don't want it and make up 
an argument that it won't happen". If that is the case: say it than I walk 
away and let you work for your own.

Any Trinity specific changes have of course to be done by Trinity developers. 
That should be as simple as putting your commits into the branch - the commit 
won't apply cleanly, but manually that's possible. I cannot do them as I don't 
know what Trinity needs and I will never ever install Trinity.

This is ridiculous. Do you seriously think that we don't take care of ensuring 
that it does not break on some hardware? Do you think that Trinity will spot 
severe bugs the KWin team has not found for their millions of users? Are you 
aware of all the steps we have to ensure that never again a driver will fail 
KWin? About the fact that we have five different compositing modes?
* OpenGL 2
* OpenGL ES 2
* OpenGL 1
* XRender
* no compositing
That KWin is able to choose the right backend based on the hardware and driver 
the user is using? That KWin can disable compositing if it notices that things 
go wrong?

yes I have as outlined above. If you want to use KWin use it, but stop the 
fork and no demands to our development team. We have enough to work without 
taking care of Trinity development. If I offer you help accept it in the way I 
offer it, but not by demanding futher things.

Cheers
