             Bug #: 54732
           Summary: cairo_copy_path converts device to user instead of
                    backend to user
    Classification: Unclassified
           Product: cairo
           Version: 1.12.2
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: general
        AssignedTo: cworth at cworth.org
        ReportedBy: benjamin at sipsolutions.net
         QAContact: cairo-bugs at cairographics.org


When the user calls into cairo_copy_path, cairo will convert the path to user
coordinates using "cairo_device_to_user". However, the path is stored in
*backend* coordinates (converted using the function
_cairo_gstate_user_to_backend).

This means that the result of cairo_copy_path is shifted by the device offset
of the target device.

https://bugzilla.gnome.org/show_bug.cgi?id=681475 is an example where this
causes troubles.
