fdo#53163 fix hatching for objects with curves

B2DPolyPolygon can contain Bezier curves, but that is not taken into
account when drawing the hatching in OutputDevice::ImplDrawHatch. The
poly-polygon is adapted already when creating metafile, because the
information about the poly-polygon containing curves is then lost
somewhere in the process. At least, when I do the adaptation in
OutputDevice::ImplDrawHatch, it has no effect and the hatching in the
produced PDF is still wrong.
