 pdfTeX and dvipdfmx introduced several special commands related to the generation of PDF files. Currently,
-only 'pdf:mapfile', 'pdf:mapline', and 'pdf:pagesize' are supported by dvisvgm. The latter is similar to the
-'papersize' special (see above) which specifies the size of the current and all folowing pages. In order to
-actually apply the extents to the generated SVG files, option *--bbox=papersize* must be given.
-The other two PDF specials allow modifying the font map tree during while processing the DVI file. They are
