FWIW, someone tried making a small demo program in C++ that used this feature: http://www.codeguru.com/cpp/misc/misc/flickerfreedrawing/article.php/c3877
I don't know why he seems to think GetBoundsRect doesn't work properly in Windows 95 and 98. It's been in Windows since the 16-bit days (3.10 I think) and in my experience it certainly works fine in Win9x. Maybe it depends on the graphics drivers.
