           Summary: add support for "recursive" xlib surfaces
           Product: cairo
           Version: 1.4.1
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: xlib backend
        AssignedTo: cworth at cworth.org
        ReportedBy: desrt at desrt.ca
         QAContact: cairo-bugs at cairographics.org


i'd like support for "recursive" xlib surfaces in cairo.  that is, surfaces
that have the following semantics:

1) when used as the destination of a draw op, any child windows that clip the
parent are simply drawn over top of

2) when used as the source of a draw op, any child windows that clip the parent
are simply taken as part of the source image data

this corresponds exactly to the IncludeInferiors XRenderPicture attribute
