quick fix: call qRound instead of casting to int

i was unable to test the fix, because I don't have an usable kde build
environment set up, but I think i found the issue:

opacity is stored as a floating point number and the operation of muliplying it
with 100 and casting it to int sometimes leads to a number one less than is
expected - caused by inaccuracy of the floating point number.
why isn't opacity stored as an int? perhaps that would be a better fix.

it can be that <QtGlobal> must be added as an include to make it compile.
