Use
The purpose of this call is to set the values used when converting between OS co-ordinates and millipoints..
Notes
Applications that run within the windowing environment (the desktop) should not use this call. This is because other applications may rely on current settings. If the call is used, then the current values should be restored afterwards.
The default value is 400 millipoints per OS unit.
To read values, Font_ReadScaleFactor should be used.
