That one is because lmt_svg does not properly consider the

in the marker definition. I played with setting it to actual angles,
and then the output is ok.

The path in the marker has its own transform, and that seems to be
ignored by lmt_svg. (I do not see how a scale of (-1.1,-1.1) would
make it that much bigger, but I know that manually altering the values 
does nothing, so I guess that must be it).

No solution, but I hope this helps Hans somewhat...
