DefToken parameters shouldn't be evaluated, even in constructors
createXMRefs should be more selective about creating XMRefs (for XMHints or XMRefs)
\lx@setcurrenvir should be primitive, not macro
since non-stretchy is now default, make fences that contain a linebreak be stretchy
Support for XMDuals(& XMRefs) to determine whether they are visible to presentation, content, or not at all (prune the latter), this guides rewrite rules, for example
call to markXMNodeVisibility at appropriate time.
Use node visibilty to control math rewrites, not just whether it is in XMDual's content branch
updated test for XMDual rearrangement and pruning
be careful to expect XMRef more often; be careful annotating the result, particularly avoid dangling idrefs; generally avoid open, close (& related) attributes in preferring XMDual
added a copy of markXMNodeVisibility since that is needed for proper parallel markup; careful about associateID, also for parallel
be more prepared to deal with XMRef's; better style propagation, especially w/mathstyle(display|text|etc); better source-id tracking (and simpler, besides); recognize inline division as infix, when the operator has content
enhanced (& incompatible) dualize_arglist to put actual arguments on presentation side (so they inherit proper display features) by default, but also to recognize when an argument is hidden (and should be on the content side, so that it still gets included in the output)
Added a HACKY means to revert to the internal LaTeXML markup so that an object can be RE-digested (needed for \over, etal)
RE-digest the numerator of \over and friends so that they get textstyle (Risky, but I can't figure out how else); XMArg shouldn't be in textstyle; fixup XMArg and XMRef id resolution since we no longer know which one will come first; make bigops (like \int) get mathstyle and not default, since that tends to get misinterpretted
updated test, since \int gets mathstyle attribute
reworked multline, split and gathered to generate an XMDual to preserve both the (assumed) semantics, and the alignment structure; developed generalized support for cases, matrix and extensible arrows to simplify mathtools
updated tests due to changes in amsmath.sty
