Eirik Aavitsland 824d293601 QPainter: fix assert when drawing bitmaps at very near to .5 coord
The code assumed that the rounding of a floating point value, and the
rounding of the sum of that value and an integer, would always snap in
the same direction. But because of accuracy limits (independently
of the rounding function employed), that is not always the case for
fractions very near to .5.

Fixes: QTBUG-122451
Pick-to: 6.6 6.5 6.2 5.15
