This commit add the getLegendGraphic pixmap as legend in the QgsLegend.
Due to architectural QgsLegend limitation pixmap is shown of the same dimension of every single legend element (too little)

managing of getLegendGraphic popup and refresh - Developed with funding from Regione Toscana-SITA
Due the fact that WMS pixmap is too little, has been added a popup to show WMS legend in the original size
Has been added feature to refresh getLegendGraphics to every scale change due to extend modification. In this way
getLagendGraphic can be updated basing on scale and in the future also basing on viewport.

Modified QPixmap to QImage to be device independent

set absolute position due to popup is not referred to legendInterface (avoid hiding of the legend)
Added a resolution parameter in option->Canvas&Legend to instruct WMS getLegendGraphic
to get WMS legend with a good resolution for printing.
Set value to 0 to get default pixmap resolution.

Drawback in case of big resolution of the legend, it becames too big to be
correctly shown as PopUp in the QgsLegend interface.

Developed with funding from Regione Toscana-SITA
