        [Qt] Canvas shadow offset should not be affected by any transformation
        https://bugs.webkit.org/show_bug.cgi?id=50422

        On a canvas context, shadows are currently affected by all
        transformations except scaling. According to the spec:
        http://www.whatwg.org/specs/web-apps/current-work/multipage/the-canvas-element.html#shadows

        "The shadowOffsetX and shadowOffsetY attributes specify the distance
        that the shadow will be offset in the positive horizontal and positive
        vertical distance respectively. Their values are in coordinate space
        units. They are not affected by the current transformation matrix."

        NOTE: this applies only to canvas, not to box shadows.

        Add new test to ensure that shadows are correctly transformed keeping
        the relative offset to the shape.

          a lineWidth > 1 to make it easier to test and more fair among all
          ports, since there can be different transformation smoothness or
          aliasing settings.
