Method getTextDrawPoint

qcustomplot/qcustomplot.cpp:29088–29103

! \internal Returns the point that must be given to the QPainter::drawText function (which expects the top left point of the text rect), according to the position \a pos, the text bounding box \a rect and the requested \a positionAlignment. For example, if \a positionAlignment is Qt::AlignLeft | Qt::AlignBottom the returned point will be shifted upward by the height of \a

  drawn at that point, the lower left corner of the resulting text rect is at \a pos.
