Round physical dpi when calculating scale factor
(For the QT_USE_PHYSICAL_DPI use case)
The physical DPI is nominally computed from the physical
screen size, however when QT_USE_PHYSICAL_DPI is set
that size has typically been overridden with a fake
size by the user, such that the resulting DPI calculation
will yield some specific integer DPI.
Round this DPI value in order to arrive at a nice scale
factor, e.g. 144/96 = 1.5 instead of 144.01/96 = 1.5001
