\brief Text Engine for the MathML renderer of the Qt solutions package.
To enable MathML support the following code needs to be added to the
application:
\verbatim
#include <qwt_mathml_text_engine.h>
QwtText::setTextEngine(QwtText::MathMLText, new QwtMathMLTextEngine());
\endverbatim
\sa QwtTextEngine, QwtText::setTextEngine
\warning Unfortunately the MathML renderer doesn't support rotating of texts.
