It's clearly a Windows bug, so I'd mark it as broken().  If we need to
minic Windows' behaviour at some point we can review it again then.

There is benefit to always testing the region's rectangle count and
ensuring IntersectClipRect()'s retval isn't anything other than
SIMPLEREGION or COMPLEXREGION, so the other changes in the patch would
be good.
