Mozilla/mozilla/editor/libeditor/html/nsEditProperty.cpp
glazman%netscape.com 20124c5607 Allow mouse-driven resizing of images and tables in all instances of editor. 
For the default Mozilla build, this includes Composer and Mail Composition.
Embeddors willing to disable this feature should look at |nsHTMLEditor::SetIsImageResizingEnabled()|
Displays eight resizing handles plus an info box. Images are resized real-time.
Uses HTML attributes in pure HTML mode (mail composition for instance) and CSS properties when available.
Undoable and Redoable. Does not grind coffe and make a good expresso yet.
Thanks if you really read to that line.
