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
See also http://support.microsoft.com/kb/139217
"Windows maintains an accumulated bounding rectangle for each application. An
application can retrieve this bounding rectangle by calling GetBoundsRect, and
it can set this rectangle by calling SetBoundsRect. But this rectangle may not
be the smallest bounding rectangle if your drawing functions contain functions
doing text output such as TextOut. GDI does not calculate ahead of time how far
across the TextOut functions are going to draw. GDI just sets the right side of
the bounding rectangle to a large number. "

Krugle found a few possible calls to it, e.g. in bzflag and Neuroshare
http://www.krugle.org/kse/files?query=GetBoundsRect
and a whole lot of false positives.
