The Win32 GDK backend can be influenced with some additional environment
variables.
### GDK_IGNORE_WINTAB
### GDK_WIN32_TABLET_INPUT_API
If this variable is set, GTK doesn't use the Wintab API for tablet support.
If this variable is set, it determines the API that GTK uses for tablet support.
The possible values are:
### GDK_USE_WINTAB
`none`
: Disables tablet support
If this variable is set, GTK uses the Wintab API for tablet support.
This is the default.
`wintab`
: Use the Wintab API
`winpointer`
: Use the Windows Pointer Input Stack API. This is the default.
