Inset 'Xyz' is implemented by 'MathXyzInset' in 'math_xyzinset.[hC]'
Inset hierarchy:
MathInset
(abstract base)
/ | \
Dim Char MacroArg
(thing that need (for things formerly
the width_/ascent_ known as characters)
/descent_ cache)
/ \
Nest Dots Func Space Symbol Bigop Noglyph
(for thing with
nested content)
| \
Grid Decoration Delim Frac Macro Root Script Sqrt
/ \
Array "Matrix"
(base for eqnarray/align/...)
There are only two "real LyXInsets" in here:
Formula - containing a pointer to a MathMatrixInset (a misnomer...)
FormulaMacro - containing a pointer to a MathMacroTemplate
