neutrino: port rounded corner code from tuxbox CVS

Browse Source 
This allows to set all four corners separately. The default is
now to have all four corners rounded if radius is > 0 in paintBoxRel.
It also places hard coded integer numbers for CORNER_TOP and
CORNER_BOTTOM with the respective #defines.
This should make it much easier to port over code parts from tuxbox.org.
However, there are probably bugs and oversights in that I did not find
yet. Reports are welcome.
