Berthold Stoeger b068b2b0e7 statistics: replace PieSeries by QSG nodes
Since there are no disk-segment QSG primitives (one could draw
a triangle fan, but that doesn't seem optimal), this draws
into a pixmap and blits that as a QSG node.

Since this is the only series without axis, it needs a function
that returns the size of the plot area. This didn't exist, so
add it.
