patch 9.1.0133: MS-Windows: ligatures not rendering correctly 
Problem:  font ligatures don't render correctly in the Win32 GUI-version
          of gvim even when set rop=type:directx is used. Setting
          guiligatures also doesn't make any difference. This leads to
          broken font ligatures when the cursor passes through them. It
          does not recover from this, and they remain broken until you
          re-render the whole buffer (e.g. by using Ctrl+L).

Solution: the problem is that we only re-draw the current and previous
          character in gui_undraw_cursor() and only have the special case
          for GTK when it comes to rendering ligatures. So let's enable
          gui_adjust_undraw_cursor_for_ligatures() to also happen for
          Win32 GUI if guiligatures is setup correctly (all this does is
          expand the range of gui_undraw_cursor() with ligature characters).
