Update Dpi and scale factor computation
Remove pixelScale() in favor of logicalBaseDpi(). Compute scale factor
based on logical DPI and logical base DPI, or optionally based on the
physical DPI.
Add policies for running the scale factor and adjusting the logical
DPI reported to the application. The policies are set via environment
variables:
QT_SCALE_FACTOR_ROUNDING_POLICY=Round|Ceil|Floor|RoundPreferFloor|PassThrough
QT_DPI_ADJUSTMENT_POLICY=AdjustDpi|DontAdjustDpi|AdjustUpOnly
QT_USE_PHYSICAL_DPI=0|1
