Detailed Description

Round-trip tests for the .wxmx content.xml (the MathML-like math format).

The math cell classes each have a ToXML() and a matching MathParser handler, with various parameters and special cases. This checks that parsing a content.xml into a cell tree and serialising it back is a fixed point: the serialisation of the reparsed tree must equal the first serialisation. If any cell class loses or changes information on parse or serialise, the two differ.

Inputs: the real content.xml corpus (in test/fuzz/corpus_mathparser, exported by actual wxMaxima) for realistic coverage, plus a crafted fragment that exercises the math constructs the corpus happens not to contain (sqrt, integral, sum, matrix, abs, conjugate, sub/superscript) so every ToXML class is covered.
