We can check the KDE version with a #if KDE_IS_VERSION(...), so no need 
for a configure check.

Another, and probably better, option is to monitor the QKeyEvents we 
receive and then remember the modifier states each time they change. 
That should be simple enough as we already have an event filter that 
could do that.

A third option is to fix the key event handling for the canvas, as at 
the moment, implementing KisTool::keyPress/keyRelease doesn't deliver 
any key events to the tool. That needs doing at some point. Then the 
tool could just change the cursor each time it sees the state change.
