• Added more details to some DVI warning messages.
• Added some further information to the manual page.

• Fixed a rounding issue that could lead to slightly bigger text extents (issue #256).
• Added the macros {?pageno}, {?svgfile}, and {?svgpath} to the dvisvgm special commands.

• Fixed potential segmentation faults triggered by missing font files (issue #241).
• Fixed a GLIBCXX assertion error occurred if dvisvgm is built with _GLIBCXX_ASSERTIONS enabled (issue #242).

• Several minor code improvements.

• Fixed a bug that could prevent reading the output of subprocesses (issue #232).
