Detailed Description
Support for plug-in view content scaling, to be implemented by the VST3 IPlugView class.
On Windows, if a process is "DPI-aware" and the system DPI setting is different from the default value of 96 DPI, the application is responsible to scale the contents of its windows accordingly, including child windows provided by 3rd party plug-ins.
This interface is used by the host to inform the plug-in about the current scaling factor. The scaling factor is used to convert user space coordinates aka DIPs (device-independent pixels) to physical pixels on screen.
The plug-in has to be prepared to deal with the following scaling factors:
96 DPI = 100% scaling (factor = 1.0) 120 DPI = 125% scaling (factor = 1.25) 144 DPI = 150% scaling (factor = 1.5) 192 DPI = 200% scaling (factor = 2.0)
On Windows 8.1 or later DPI settings are per monitor. The scaling factor for a window can change when it is moved between screens.
