Cary Clark cb6bef0ad5 Update bookmaker 
- This update includes font documentation.
SkFont_Reference.bmh was generated by running:

  bookmaker -b docs -i include/core/SkFont.h -t

This creates a placeholder
for examples and additional documentation.

- More work done to exclude experimental/private
symbols.

Symbols that include "experimental_", "legacy_",
"private_", "temporary_", "deprecated_" as part
of their name (case-insensitive) are not
referenced by the on-line docs and don't need
comments.

Tables built for online only include public symbols.

- Better links for constructors, destructors, operators
- Fixed some minor public interfaces
- Removed _const crutch on operators
- Keep includes inside 100 columns
