    app: Bug 631619 - Drawing artifacts spread by paintbrush outline on canvas
    
    Add a transform matrix to GimpCanvasBoundary and get rid of the whole
    BoundSeg transform code in boundary.c and gimpbrushcore.c, it was
    impossible to get this right on that level. Also fix te extents of
    GimpCanvasBoundary os it leaves no artifacts.
