            Bug ID: 275168
           Summary: shadowsIgnoreTransforms should negate the vertical
                    shadowOffset on Cocoa ports only

          Hardware: Unspecified
                OS: Unspecified

          Severity: Normal
          Priority: P2
         Component: Layout and Rendering

For Cocoa ports the coordinates system is flipped (the origin is the bottom-left corner). Usually the coordinates system is unflipped by moving the origin to the top-left corner. When GraphicsContext.shadowsIgnoreTransforms() is true this means the coordinates system is still flipped. In this case the vertical shadow offset should be negated.
