winapih only means that this is the file where the declarations of the 
Windows API functions reside which are used (and implemented) by the LCL 
on all plattforms (even on Windows the routines there are forwarders to 
the real Win API functions). So if Get-/SetScrollInfo is implemented and 
works for e.g. Carbon you can use it.
