Do not round (mask) the decoration corners if the window aligns to a screen corner.
This has two advantages:
- Fitt's Law applies for resizing windows
- Prevents accidentally hitting buttons of maximized windows behind the active window

Hasn't been tested with xinerama setups but this should work as well. Hopefully
someone can test it before KDE 3.4.
