Detailed Description

       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:

       #include <qwt_mathml_text_engine.h>

       QwtText::setTextEngine(QwtText::MathMLText, new QwtMathMLTextEngine());

       See also:
           QwtTextEngine, QwtText::setTextEngine

       Warning:
           Unfortunately the MathML renderer doesn't support rotating of texts.
