As of now, the parameter is unused, but may be needed in the future.
I'm adding it now so that in the future both API and ABI remain
backwards compatible as long as possible.
This is a backwards incompatible change.
Replace all occurences of unsigned int and unsigned long with size_t.
This is a backwards incompatible change, as the signature of many API
functions changes.
- Add more information to the documentation front page
- Document how to build the documentation
- Clarify the tutorial a bit and remove some quirks
- Bring README.rst up-to-date
- Small enhancements here and there
