BoundingBox, for instance when using \mathbb{})
- Moved the whole "LaTeX eqn to image" conversion into the C code,
turning the C program (renamed from pngmodify to eqn2img) into
a standalone utility (e.g. echo '\sqrt{2}' | eqn2img -o
eqn.png).
- Added colour options (-c -b and -t).
- Fixed bug causing segfault when adding space _above_ an image.
- Fixed image reusing bug (in 0.2 image reuse didn't work across
separate files when processing files outside startup cwd).
- And some other minor bugs and cosmetic changes.
- Makefile added to distribution
0.2 - First official release, completely rewritten code.
