Yes, all existing styles are saved in CSS.

You can remove unnecessary styles by calling DeleteUnusedStyles.

RichViewActions automatically call this method for the loaded documents.

But it does not remove styles that have Standard property = True, i.e.

initial styles.

Moreover, the 0-th style is very important when saving CSS, because for

other styles only a difference from it is saved. So the proper choosing of

properties of the 0-th text style can greatly reduce CSS size. For

RichViewActions, it can be done in TrvActionNew.OnNew event.

The important drawback of DeleteUnusedStyles - it may delete styles that

used by deleted content (stored in undo buffer). So, it you call it for

editor, call it with ClearUndo.

Yes, things may be improved here. It's in my to-do list:

- to make undoable version of DeleteUnusedStyles

- to avoid saving unused styles in CSS.
