hrev46710 adds 5 changesets to branch 'master'
old head: fed5e6126b1340b5f40dee2570f12c0c651f71da
new head: 2c906df2174c1d0c8befc67cb0b61e789dd2eb82
overview: http://cgit.haiku-os.org/haiku/log/?qt=range&q=2c906df+%5Efed5e61
----------------------------------------------------------------------------
ce30469: HaikuDepot: Simple TextListener interface, not yet used.
b7e8a24: Paragraph: Added Remove(), untested.
13d17b5: TextDocument: Implemented Remove(), untested.
Also some refactoring for ParagraphAt() into a separate ParagraphIndexFor(),
used by the former, since often an index is needed.
315dee6: TextEditor: Resolve TODO and call Insert() and Remove()...
... which both already exist in the TextDocument API (stubbed out or
untested as they are).
2c906df: Text stuff: Bugfixes in Insert and Remove methods
Still not well tested. Also some way to trigger the layouts to adopt to
the changed document paragraphs. Not yet via the new TextListener.
