- 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 TBR=reed@google.com Docs-Preview: https://skia.org/?cl=171900 Bug: skia: Change-Id: I93b229c6625d800604671e05b82a14c06cb906d2 Reviewed-on: https://skia-review.googlesource.com/c/171900 Reviewed-by: Cary Clark <caryclark@skia.org> Commit-Queue: Cary Clark <caryclark@skia.org>
