RichView.RVData.DrawItems is a list of TRVDrawLineInfo objects.

These objects represent formatting in thr document.

Each non-text item corresponds to one such object.

Text item corresponds to one or more (if it is wrapped) such objects.

This object has properties:

ItemNo - index of item linked to this object

Offs - offset in this item (valid for text)

Length - length of text (valid for text)

(meaning of (ItemNo,Offs) is similar to parameters of SetSelectionBounds)

FromNewLine - true if this items starts a new line.

This information is enough to implement line-by-line text export.
