    VCL canvas: fix clipping of gradients (related: tdf#115142)
    
    When using the presenter console, the secondary screen has
    a small view of the current slide, which is called a "Pane" in sdext.
    
    Clipping for this is done by sd::presenter::PresenterCanvas, which wraps
    the full-screen VCL canvas and has a MergeViewState() to intersect
    the clip region.
    
    The VCL canvas has a bug in its gradientFill() implemenation where it
    overrides the existing clip on the OutputDevice instead of intersecting
    it.
    
    This properly fixes the bug that was wrongly and badly attempted
    to be fixed by commit 99e373cd4c78084ded349f3e3de7b0504af2dd90.
