vcl: renamed OutputDevice::PaintLineGeometryWithEvtlExpand()

I asked on the LO dev mailing list what Evtl means and what is being
expanded, and Michael Stahl kindly responded:

>  "Evtl" usually means German "eventuell" which means "possible" or
>  "optional" (i.e. totally different meaning from English "eventual").

So in other words, it means paint using line geometry and optionally
expand. Or in other words, it just draws a line using a B2DPolyPolygon.
Thus, I have renamed it to drawLine(), which is a private function of
OutputDevice. I think this makes it somewhat clearer :-)
