           Summary: Transparency should be optionally flattened to a new
                    path rather than bitmap
           Product: cairo
           Version: 1.7.5
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: postscript backend
        AssignedTo: ajohnson at redneon.com
        ReportedBy: alexandre.prokoudine at gmail.com

Currently PS/EPS surface flattens transparency to a bitmap. This can make a
resulted file much larger than it could be. A good solution would be to flatten
transparency in overlapping regions to new paths that have opaque fill matching
the transparency projection.
