Fix screenForGeometry on a corner case 

QRect only deals with integers, and I had a window set on the corner and
without a size. When this screen was created, it was reported to be on the
wrong screen, thus created there wrong.
The reason for this is that ::center is not prepared for this use.
QRect(QPoint(500,500), QSize()).center() is QRect(499, 499)
