I'd move it instead of copying. WinMtfOutput as-is won't cut it, you
need to extend it to cover more modern graphic operations. Caveat
emptor, that might require extensions to the internal StarView
metafile format then with some ripple-effects.

Another (IMO better) option is to convert it into a drawinglayer
primitive filter. Armin on Cc for further details on that topic.

Nah, that was referring to dump cppcanvas - getting rid of EMF+ there
is a useful first step.
