           Summary: Gradient pattern with matrix transform causes error
           Product: cairo
           Version: 1.5.7
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: quartz backend
        AssignedTo: cworth at cworth.org
        ReportedBy: richard at imendio.com
         QAContact: cairo-bugs at cairographics.org

Trying to run GTK+ on quartz with the clearlooks theme produces an error in the
terminal, and vertical scrollbars are not drawn. I will attach a small testcase
that uses the same code as clearlooks, using only cairo.

The error is:

<Error>: CGBitmapContextGetBitsPerPixel: invalid context

and from what I can tell it's from the fallback surface code, that wants a
bitmapcontext but probably gets a real context?
