           Summary: Gradients are not rendered (correctly) under certain
           Product: cairo
           Version: 1.1.1
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: pdf backend
        AssignedTo: krh at bitplanet.net
        ReportedBy: jlt_fdo at shamrock.dyndns.org
         QAContact: cairo-bugs at cairographics.org

The reason is as far as I can tell that the pattern matrix is not converted to
device space. This results in tiny, unvisible patterns if the device and user
space do not have identical scaling factors.

(I tried multiplying the x and y cordinates by width and height and it gives the
expected results for a normalized user-space.)

Test case: the gradient test case.
