I commited some fixes for the kwin4 and lskat issues raised on the list. Maybe 
someone can test them - not that I seriously bugged them...

> > KWin4:

The game now tries to figure out a the maximum framerate the computer can 
handle and adjust itselft to this (takes some seconds to get an average). Of 
course with lower framerate the animation gets more jumpy. However, if you 
are just a bit too slow this seems to help as the CPU load is decreased. 

I dont think we can do anything else here. KWin4 animates all pieces (42 
sprites) in the intro. This is more than Qt/QGVcan handle (on X11?)  [btw I 
would like to see this on Windows, whether the performance is better there - 
anyone has a windows version yet?].

We optimized the QGV stuff so much here on the list that  I think we have to 
generally face the fact that QGV is not really suitable for games. I think it 
is too powerful  and thus too slow with all the transformations, event 
handling, etc. it offers.

I also sped up John's reflections a bit. But although looking super cool I 
fear they are only useful on very fast computers.


> > * game view isn't centered
The views in kwin4 and lskat are centered now. I am personally not sure that 
this looks better but it fits in the theme of the other games now.

Here btw I noticed that you can rotate and shear a QGraphicsView but you 
cannot translate it if the scene is smaller than the view, that is has no 
scroll bars. Qt alwas cancels the translates() [by setting the leftIndent] 
and left aligns it (which probably/maybe makes sense because otherwise the 
background would be moved too)
