While it's true that Math uses EditEngine and EditView I'm not convinced
the actual change should be _inside_ those, EditEngine is already a hard
to handle beast and you'd have to add yet another mode to travel along
lines and paragraphs to highlight matching parentheses. Maybe the
ScInputHandler::UpdateParenthesis() code in
sc/source/ui/app/inputhdl.cxx might help as an inspiration how it could
be done from outside; if you could implement that inside EditEngine
without too much trouble that would be the best, otherwise I'd go for
a similar external solution. Fortunately a single Math edit usually
isn't overly long, otherwise obtaining and travelling the text whenever
the cursor stops moving would be too much overhead.

Or maybe someone has a good idea how to implement that in EditEngine? :-)
