assuming it didn't make the release (which happened 1 week after the changes 
were made), this implies we rely on beta testers and the developers aren't 
paying attention to their own applications. this surprises me.

both look good, and as you noted in the reviews they actually simplify the 
code in the process. i've processed both reviews and they should go into the 
4.10 and master branches imo.

obviously up to the kwin devs, but the x property approach should work and 
then there's no special code path to worry about: all shadows will be handled 
the same way. it would also allow the use of code in the plasmagenericshell

i don't know about this one, as i'm not familiar enough with the internals of 
kwin's tab box .. i'm sure Martin or Thomas can offer direction here though.
