Distribute the literate prose from the old combined scrollbox-tabbar.org
into three individual module org files:
- scrollbox.org: ScrollBox class, render, scrollbars, bug fixes,
plus the combined test suite (tangles scrollbox-tabbar-tests.lisp)
- tabbar.org: TabBar class, navigation, keyboard handler, render
- container-package.org: Package definition and exports
The old scrollbox-tabbar.org is retained as a documentation archive
with all code blocks set to :tangle no and a redirecting note.
Fixes the draw-scrollbars code block to use the post-bugfix version
(with layout-node origin offset ox/oy), matching the working code.
All 13 test suites pass at 100%.
