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()
or .cloneWith() so that any further changes remain local to the scope.
Other functions creating a clone include mathstyle(), fontFamily(), sup(),
sub(), cramp(), etc...
A scope is defined by:
- an explicit group enclosed in braces
{...} - a semi-simple group enclosed in
\bgroup...\endgroup - an environment delimited by
\begin{<envname>}...\end{<envname>}
