adjust gradient drawing in vclcanvas (tdf#144073)
For whatever strange reason the drawing does not use the given
geometry, but something bigger. When I added direct drawing using
VCL in a46cb5dc607d1d1af402ff3e8fce731e7427854d I naively assumed
that the drawing area for the gradient would be the given area.
