Hi Ludovic,

yes, good catch. So, this calls for a bit of debugging - are
you in? 

I'd suspect something like bForceOne/bForceTwoPixel to fire
in
svx/source/svdraw/svdobj.cxx:ImpPrepareLineGeometry(). It's
more
unlikely that the SvtGraphicStroke in eps.cxx is
incorrectly
interpreted - rather, that this object comes in with wrong
values
already.

And still my statement holds, that things like this will be
much
easier to tackle after the drawing layer rework is
finished.

It's still on topic here - though you might want to jump
into irc
(#dev.openoffice.org on freenode, I'm thorsten there), for
more
interactive discussions.

I've taken a quick look already, I'll see if I can get in
and  
understand how this piece of code works, and try something
useful  
(which is far from sure !). But before wasting too much of
my time  
(and yours), any hint on when the new drawing layer is
planed to be  
here ?

Cheers,

Ludovic.
