Comment 18 for bug 500125

Proposing to close this report as 'Invalid' in Inkscape:

1) "default export resolution": as stated in the preferences this
   applies to *bitmap export* not export in general.
   The internal scale is fixed (by default) to 90 dpi:
   <http://tavmjong.free.fr/INKSCAPE/MANUAL/html/Coordinates.html>.
2) "selfscaling" bug is not related to Inkscape:
   different solution already implemented in UniConvertor trunk.
3) "There is "undefined" stroke of objects imported from .plt files."
   The fill and stroke attributes are correctly assigned and
   not 'Unset' (You have to enter the top-level group to select
   the object itself - groups do have fill and stroke attributes
   unset per default).
4) ""Undefined" stroke must be zero (none)."
   Again this must be addressed by UniConvertor. OTOH the current
   attributes are the most logical thing to use when converting from
   a plot file (line-based) to SVG - at least IMHO.

@tuxcnc - what do you expect to get if fill is 'None' and stroke is 'Unset'? (hint: the path will not be visible):

UniConvertor output:
(…)
<g>
 <path style="stroke:#000000; stroke-width:0.283286; fill:none" d="…"/>
</g>
