- Fix now failing download source service, that is don't do this

- Update to fig2dev version 3.2.6a (Patchlevel 6a (January 2017))
NEW FEATURES:
o Distribute transfig.pdf. No need to build it from the TeX sources.
o Enable reproducible build for svg output.
o Set the creator to fig2dev, not to the path by which fig2dev is
invoked.
BUGS FIXED:
Ticket numbers refer to https://sourceforge.net/p/mcj/tickets/#.
o The svg output now produces correct patterns and pie-wege arcs.
Property names instead of style attributes are used. Hollow arrow
heads are really hollow, not filled with white. In the PostScript
output, this might also clip a bit of the filling underneath an arrow.
o tikz output: Re-use \dimen \XFigu if it is already defined. Ticket #3.
o tikz output: A pattern in an object with line width zero and the
stroke color equal to the fill color would produce a white fill.
The tikz output now does not try to be smart and puts a pattern, even
if the result is equal to a solid fill. Ticket #1.
o pict2e output: Standalone tex-files always include color.sty. #2.
o pict2e output: A pattern with stroke color equal to fill color is
rendered as a solid fill.
o Compiles when gnu iconv and standard iconv are present.

- Update to fig2dev version 3.2.6 (the successor of transfig)
o Add compile switch --enable-versioning and script update-version_m4,
to create version string from source control system
o tikz output: Support -G (grid) option. Make \XFigwidth and \XFigheight
only scale coordinates, not line widths; Do not set unnecessarily
\color{black} on text.
