new Context()private
This class contains the rendering context of the current parse level.
It also holds information about the parent context to handle scaling adjustments.
When a new scope is entered, a clone of the context is created with .clone()
so that any further changes remain local to the scope.
A scope is defined for example by:
- an explicit group enclosed in braces
{...} - a semi-simple group enclosed in
\bgroup...\endgroup - an environment delimited by
\begin{<envname>}...\end{<envname>}

If true, unique IDs should be
generated for each span so they can be mapped back to an atom.
Can also be an object with a seed field to generate a specific range of
IDs. Optionally, if a groupNumbers property is set to true, an additional
span will enclose strings of digits. This is used by read aloud to properly
pronounce (and highlight) numbers in expressions.
