implemented a system to track what portion of a document is affect by an editor action. Used that system to help solve extensive whitespace handling problems, ans also problems with caret placement in response to returns (this lattter fix for html editors only - plaintext coming later). Fixed numerous list bugs involving outdenting, unlisting, and splitting lists. Checkin addressees these bugzilla bugs: 2073 & 12337 - whitespace trouble when typing (you can end up with all nbsp's instead of spaces)

fix for 20457: deletion in editor pretty darn screwy. Lots of changes to improve this. Document modifying entry points in editor now go thru a standard sandwich, which allows tracking of what changed in the doc, which allows proper post-processing of what changed. Also, all deletions now go thru the rules code, if applicable. Also some bugs in tracking the changed document portion have been fixed. Finally selection setting after a delete is improved.

0. possible fix for Sun build bustage. 1. IsEditable is much less hacky. It basically says: 1. if the node is a special bogus text node, it's not editable 2. if the node is a text node with only newlines, then it's not editable 3. if the node has no frame associated with it, then it is not editable 4. otherwise, it is editable. As part of this, I had to make IsEditable non-static. This had some cascading effects on static methods that called IsEditable, which likewise had to be made non-static. 2. SetTextProperties now works when the endpoints are leaf nodes (like images), not just text. Charlie, you should put this through some stress cases.

fix for 20457: deletion in editor pretty darn screwy. Lots of changes to improve this. Document modifying entry points in editor now go thru a standard sandwich, which allows tracking of what changed in the doc, which allows proper post-processing of what changed. Also, all deletions now go thru the rules code, if applicable. Also some bugs in tracking the changed document portion have been fixed. Finally selection setting after a delete is improved.

implemented a system to track what portion of a document is affect by an editor action. Used that system to help solve extensive whitespace handling problems, ans also problems with caret placement in response to returns (this lattter fix for html editors only - plaintext coming later). Fixed numerous list bugs involving outdenting, unlisting, and splitting lists. Checkin addressees these bugzilla bugs: 2073 & 12337 - whitespace trouble when typing (you can end up with all nbsp's instead of spaces)
