This adds a series of patches related to https://bugreports.qt.io/browse/QTBUG-53022 for Windows to allow enabling experimental support for fractional DPI scaling.
In addition, a patch to fix https://bugreports.qt.io/browse/QTBUG-72504 (which is set to be in Qt 5.12.3) is included..
The exact list of patches is as follow:
These series of patches adds the option QGuiApplication::setHighDpiScaleFactorRoundingPolicy to control how the DPI scale factor is rounded (or not), which can also be overridden by the environment variable QT_SCALE_FACTOR_ROUNDING_POLICY. The options include:
- Round: Round up for .5 and above.
- Ceil: Always round up.
- Floor: Always round down.
- RoundPreferFloor: Round up for .75 and above.
- PassThrough: Don't round.
Currently the default option is explicitly set to Round to obtain the old behaviour (where 1.5x is rounded to 2x). Though we can consider switching the behaviour to RoundPreferFloor (where 1.5x is rounded down to 1x), since users with 1.5x scaling will tend to complain that the UI gets too large and rounding down can be a more acceptable behaviour.
The actual config option for user to enable the PassThrough option is to be added in a separate change.
