Placing an accent (say `\bar`) over a single macro-defined command
(say a `\Phi`, or a `\mathbf{x}`) caused the engine to crash.
The accent logic was incorrectly re-compiling the already compiled
argument recursively. We were just lucky in other cases.

Math formula in block quotes, footnotes, headers, etc. now adapt to the current document size instead of using a fixed value. The adjustment is based on the eye (ex-height) for consistent optical alignment.
Mere typo seen in passing, only affecting debug.
…a macro The columnalign option is modified (converted to list), but might be the same original object from a TeX-like macro. One invocation of the macro shall not affect the subsequent one.
The "cap" unit is proposed in CSS4 Draft and makes sense for cap-height font adjustement. Both "ex" and "cap" shall be based on font metrics when available, and only measure a character as a fallback heuristic. Some fonts may not have the necessary Latin characters, in which case we shall resorti to a decent fallback (as per CSS recommendations).
The original version only parsed a subset of the table. Let's handle the complete OS/2 font table for all versions 0 to 5.

Supporting `\sqrt[degree]{radicand}` requires support from the parser
due to the unusual syntax with a math expression between square brackets.
