           function rounds down to a number that the device can support.

           are equal).
 
Return Value

Comments
 
Windows calls this function just before a non-Windows application starts as
well as before switching back to Windows. When switching back to Windows,
InitScreen sets the display to a text mode that Windows supports. This
ensures that Windows can correctly display the Windows screen.
 
Windows switches back to Windows when the non-Windows application terminates
or when the user switches away. If the user switches away, Windows calls
InitScreen after saving the application screen and calling the DisableSave
function.
