Rearrange2

[brucemiller]

This PR rearranges a bit of code to more appropriate modules; more consistent utilities and naming. Improves the tracing and debugging commands.

It looks great overall, but now that you have raised awareness to \tiny ... \Huge having moved out of TeX.pool.ltxml in #2358, I worry they will quietly disappear in cases they used to work in before. Ideally, we would like to make them widely available to all .cls cases in latexml that used to work in the past.

So at the least we should add them to OmniBus.cls.ltxml?

But I also wonder if they wouldn't be a reasonable fit in the font-related block of LaTeX.pool.ltxml itself for now, until the next evolution of .cls support.

On a closer look, the bindings that don't use LoadClass, and are hence top-level class definitions, are:

• report.cls.ltxml, article.cls.ltxml, slides.cls.ltxml, standalone.cls.ltxml,book.cls.ltxml

And possibly some third-party definitions external to the LaTeXML repository, but we don't have full visibility there. I see standalone loads its raw variant which loads article, so that is OK.

So there is a remaining change of behavior only in the slides.cls.ltxml case, for the in-repo bindings.

I should flag that I plan to open a related issue: \tiny, ..., \Huge are responsible for changing \baselineskip, and the fact that LaTeXML does not do that has very visible side effects with TikZ.

Good catch! slides is the only one not based on LoadClass. I kinda hated the duplication, but theoretically classes define these differently; and having them defined when the "shouldn't" be causes confusion to the (eventual) latex.ltx loader.
@xworld21 I'm looking forward to further tikz refinements; there's going to be a big push on all that stuff in the future.
