Fix bug 2637
* src/graphics/GraphicsConverter.C
(Converter::Impl::Impl): Don't call the default converter directly,
but create a temporary script with build_script() as for the
configured converters. This makes sure that the file name does not
need to be passed on the command line anymore.
(build_script): This cannot fail anymore, so change the return type
to void
(build_script): Use build_conversion_command also for the default
converter. This has the advantage that the special code for moving
${outfile}.0, ${outfile}.1 is actually used for ImageMagick's convert.
(build_conversion_command): factored out from build_script
