Detailed Description

A matrix power A^^n is marked as one: A^⟨n⟩ (GH #1005).

In Maxima A^n of a matrix is the elementwise power, so an A^^n drawn as a plain exponent looks exactly like a different result. Until this, the only place the difference survived was copy as text: the screen, LaTeX, MathML and RTF all showed A^n, and saving and reloading a .wxmx lost it entirely.

The maths is hand-written XML of the shape wxMathML.lisp emits, parsed by the real MathParser, so no Maxima is needed.
