Detailed Description

Pins the LaTeX export of an integral's "d" (GH #972): the "d" of "dx"/ "d\theta"/... must render upright (\mathrm{d}), not in math mode's default italic.

wxMathML.lisp's wxxml-int emits this "d" as its own ("special constant") tag – the same style e/i/pi/inf/minf use – but unlike those, "d" fell all the way through TextCell::ToTeX()'s early-returning TS_SPECIAL_CONSTANT branch as a bare, unstyled character, since none of that branch's specific cases matched it.

The math content is two hand-written <in> (IntCell) XML fragments, parsed through the real MathParser exactly like wxMathML.lisp would emit them for the definite and indefinite forms of integrate() – no live Maxima needed.
