physikerwelt 5713e1966e Fix rendering of underOver
We recently changed the internal treatment of macros
 to include the `\` in the macro names.
The respective code checked if the macro name had the letter 'o'
 at position 0. Now, this is position 1.

* Check for the entire start of over
* Output an error if the macro name does not star with under
  or over
* Remove dead code

Fix: handling of named operators
In I94887f6ccb45072180a318776ae96aead8658a18 named operators that render
 as their tex command e.g. \gcd -> gcd, were not taken into account.

Remove additional \ in operator names.

Remove menclose in cancel rendering
Chrome and similar browsers do not support the
menclose tag. This change introduces a css polyfill
suggested in

https://github.com/w3c/mathml-core/issues/245#issuecomment-2410676518

but keeps the mencose rendering since FF does not
support the polyfill

Use cell based table rendering
* Add hline search in matrix construction:
** This avoids a second scan later for the cost of some
   memory overhead
* Parse | in array column specification
* Add CSS based table lines as done by TMML, cf.

physikerwelt 9a27d92c09 Add missing apply after operatorname
* Reapply the logic of \log rendering to \operatorname
* Deduplicate applyFunctionDetection

Note this still does not solve the rendering problem for
operator names with more than one letter as these generate
mrow elements with single letters. Those are not rendered
with space in FF.

Implement basic column info parsing
* For each letter l c or r that is found in the
  column spec the respective mtable alignment
  information is passed
* if the align information is given externally
  the info will still be ignored

Fix heuristic that adds bold-italic
As indicated in the comment the code intents
to add "additional italic mathvariant
when bold already". However, effectively it
always added an additional -italic when
any mathvariant was given.

* Only add '-italic' if mathvariant is 'bold'

Implement hline support for matrix
In MathML outer table boarders are represented with the
notation attribute of an menclose element. The inner
boarders are represented by the rowlines attribute
of the mtable element. The rowline element accepts
a space seperated list of row boarders. In LaTeX
the bottom line is represented by a new matrix row
that only contains \hline.

This change discover \hline elements in matrix cells
and then determines if it is in the first or last line.
When it is in the last line, the line is removed to avoid
an empty <mtr /> in the output.

Moritz Schubotz (physikerwelt) 5fa3d6bfe5 Clean matrix arguments
Originally the parse tree was a binary tree, from that
time matrix element were put into that data structure.
This was partially undone, but not full which leads to some artifacts
in matrix cells.

One of the problem is that due to the binary parse
tree structure the postprocessing did not correctly
identfy \limits.

This change changes reduces nesting from matrix, and regards
matrix instances as two-dimensional TexArrays.

Pass font options in underOver
Following the same argument as for accents,
font options should also be passed in underOver
constructs.
