Timo Kreuzer e4aff98165 UserScrollDC (complete rewrite):
- include the region that could not be copied (invisible before) into invalid region
- use less regions and calculations
- return the type of the invalidated region (used by NtUserScrollWindowEx)
- Remove LPtoDP and DPtoPL. Everything is now in logical coordinates.
NtUserScrollDC:
- use SEH for buffer transfer
NtUserScrollWindowEx:
- use SEH for buffer transfer instead of MmCopyFromCaller
- use SEH to write back to usermode
- return the type of invalid region not of the invalidated region (nothing if SW_INVALIDATE is not set)
- use members of WINDOW_OBJECT instead of calling IntWinListChildren
Use hungarian notation for variables
