A class for drawing markers.
A marker can be a a symbol, a label or a combination of them, which can be drawn around a center point inside a bounding rectangle.
The setSymbol() member assigns a symbol to the marker. The symbol is drawn at the specified point.
With setLabel(), a label can be assigned to the marker. The setLabelAlignment() member specifies where the label is drawn. All the Align*-constants in Qt::AlignmentFlags (see Qt documentation) are valid. The alignment refers to the center point of the marker, which means, for example, that the label would be painted left above the center point if the alignment was set to AlignLeft|AlignTop.
