 pdf2svg is using the wrong call to poppler..

 lines now come out with a thickness of 1 instead of 0.398.  according to
 the irc channel:

 <wagle> if pdf2svg uses poppler, and now draws lines too thick compared to
 6-9 months ago, is poppler the one at fault?  The lines used to be 0.398
 thick, are now 1
 <adrianj> wagle: pdf2svg should be calling
 poppler_page_render_for_printing() instead of poppler_page_render(). The
 former is for use with cairo vector surfaces. The latter for image
 surfaces.
 <adrianj> The stroke adjust feature will cause lines < 1 wide to be
 adjusted to 1 pixel wide but only for image surfaces.

 here's the patch:
