In general, TextFrame is a Writer concept, what you want to improve here
is the shape text of drawinglayer shapes, I guess. ;-)

Yes, it's editeng that provides the shape text functionality in
Impress/Draw.

include/editeng/eeitem.hxx provides the identifiers for editeng
properties, EE_CHAR_GRABBAG and EE_CHAR_CASEMAP are quite recent
additions, they may serve as a good example on how to add a new editeng
character (i.e. when the property is not for the paragraph, but only for
a portion of it) property.

That's the document model. Once you are done with that, the next steps
are dealing with UNO API, layout, filters, tests, UI -- but one step at
a time. :-)
