fix bugs exposed by documenting SkImageInfo

- More rigorous symbol identification creates additional
links, and finds spurious errors like unnecessary
parentheses.

- Fixed code to allow preprocessor directives in
#Code blocks (still more to do).

- Fixed examples waiting on fiddle updates.

- Make SkImageInfo officially documented (update in status.json).

- Fixed enum indentation.
