           Product: cairo
           Version: 1.9.7
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: blocker
          Priority: medium
         Component: freetype font backend
        AssignedTo: david at freetype.org
        ReportedBy: chris at chris-wilson.co.uk

The user needs to notify cairo when they have deleted the underlying resource
so that cairo can drop all associated caches and handles.

When creating an ft_font_face() from an FT_Face we key on (long)FT_Face, and so
it is possible for a new FT_Face to have the same key if the original face is
destroyed and Cairo remains blissfully unaware.
