1. All stuff to generate documentation is moved from 'gen_iface.py' to a separate module 'gen_docs.py'. It contains several new structures to support maintenance of the documentation:
categoriesList - A list of the categories and an optional description.
docsMap - A dictionary that assigns each method to one of the categories.
docOverrides - A dictionary that can be used to replace the docstring from the iface file.
docSubstitutions - A dictionary that can be used to replace a few words from the docstring in the iface file.
extendedDocs - A dictionary that can be used to add extended documentation.
sinceAnnotations - A dictionary that can be used to add '@since' annotations.
2. Documentation is reformatted and updated:
- Added a table of contents.
- Broke the methods into sections.
- Added docs for previously undocumented methods.
- Altered docs that were unhelpful or misleading.
- Added '@since 3.1.0' notes and '@since 3.1.1' notes.
- Altered docs which contained references to Scintilla macros or other problematic text.
Closes#17680.
