3.1 (maybe earlier) supports 4 level grayscale.
3.2 - ?
3.3+ supports 16 level.
This is using the ScrDisplayMode (pre 3.5) or WinDisplayMode (3.5)
calls - same call, trap, API, different name.
WinScroll* should work on any mode the above calls can access as
should any other Win call.
(e.g. Visors can do 16 level in hardware, but only 4 in software, so
the call should work on 4 level, but I haven't verified all the calls).
