Subject: [PATCH] Fix misaligned selection region with text when centered
If the text is centered, the x/y position in the selection QRectF may
be a multiple of 0.5 which is rounded up. This rounding causes
misalignment of the selection region with the text.
The alignment is fixed by using qFloor on the x and y components.
