TWin32WidgetSet.SetScrollInfo modifies the content of the ScrollInfo
ScrollInfo.nMax := Max(ScrollInfo.nMin, ScrollInfo.nMax - 1);i.e. nMax is typically decremented by 1, with *every* new call!
IMO this is *not* a desireable behaviour.
Iff there exists a difference between the LCL and Win32 interpretation of the TScrollInfo record, this should be handled in a way that does not invalidate the user supplied information.

It looks like this is only a wrong implementation of the constraints, described in the WinAPI docs.
