I have pondered the whole business a bit last night and I think the
following is a feasible approach in the next unstable series:
1 improve the parser to interpret some of TeX's typesetting primitives
properly including support for drawing on screen
2 make the set of predefined macros "dynamic"
(2a put them in an extern file (?))
(2b include metrics information for faster drawing (?))
3 on input of an unknow macro (be it from a file or manually):
3a use Jules's TeX magic to determine what TeX would do
3b try to parse it
3c if the latter succeeds:
- add the macro the set of "predefined macro"
- use it as \lor etc is used nowadays.
otherwise
- display it as red text "as usual"
(3d offer a possibility to add the new macros permanently to the
set of "predefined macros")
