Detailed Description
       Text Engine for the MathML renderer of the Qt solutions package.

       The Qt Solution package includes a renderer for MathML http://www.trolltech.com/products/qt/addon/solutions/catalog/4/Widgets/qtmmlwidget
       that is available for owners of a commercial Qt license. You need a version >= 2.1, that is only available for Qt4.

       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.
