Reimplement to return the base logical DPI for the platform.
This DPI value should correspond to a standard-DPI (1x) display. The default implementation returns 96.
QtGui will use this value (together with logicalDpi) to compute the scale factor when high-DPI scaling is enabled, as follows: factor = logicalDPI / baseDPI

Reimplement this function in subclass to return the physical size of the screen, in millimeters.
The physical size represents the actual physical dimensions of the display.
The default implementation takes the pixel size of the screen, considers a resolution of 100 dots per inch, and returns the calculated physical size. A device with a screen that has different resolutions will need to be supported by a suitable reimplementation of this function.
