wxWidgets/include/wx/msw/clipbrd.h
Vadim Zeitlin d59ceba572 1. more drag and drop and clipboard changes:
a) OLE clipboard works fine
 b) wxBitmapDataObject now accepts DIBs (but doesn't give them back :-( )
 c) bugs in sample corrected
2. wxFatalExit() replaced with wxFAIL_MSG() in bitmap.cpp and dcmemory.cpp
3. wxFrame::ClientToScreen and ScreenToClient() replaced with DoXXX() - like
   this, they don't hide the base class versions
