Optimize speed of QGL2PEXVertexArray
This function is the main performance hog when using QStaticText with
the OpenGL engine, so I've improved on it a little by removing the
conversion from (qreal,qreal) -> QPointF -> QGLPoint. Since the function
is called so often, it has an impact on drawStaticText().
