* Internal: Pass full `options` objects to makeSpan/makeSymbol.
Not just the current color. This will facilitate applying options
to built nodes in a standardized way, rather than changing all
callsites.
* Add style switching test: text and scriptstyle in the same group.
* Apply style-specific spacing using different CSS coding.
Specifically, infer style from a class on the *current* element,
rather than the parent element. Use "mtight" class to denote elements
with tight spacing (scriptstyle or scriptscriptstyle). Apply that
class automatically based on options.
* Fix#533, #534, #541.
- #534: Implement getTypeOfGroup for font groups.
- #533, #541: Improve the ways spaces are applied to lists. Since
CSS adjacency implements mathematical spacing, it's incorrect to
introduce "convenience spans" for spaces and display changes into
the generated HTML -- those spans break adjacency. Apply display
changes directly, and shift space spans into adjacent atoms.
Requires updates to two screenshotter tests, LimitControls and
SupSubLeftAlignReset. The new results for these tests are closer
to TeX output than the old results.
Also requires updates to Jasmine tests, since those assumed output
structures that have changed.
* Fix#136: Size commands generate fragments, not spans.
This is so the size commands don't hide the types of their enclosed
atoms. Addresses #136.
This slightly changes the vertical position of the Sizing test. Not
sure the vertical position matters, so change the test.
