Support for end angle in pie charts

[GoogleCodeExporter]

In addition to the start angle it would be useful to have an end angle 
(default: start + 2 * pi) which would allow to draw partial pie charts. There 
could be a switch to draw all pies either in the available range (and so more 
or less compressed) or as usual over the 2 * pi range, but then cut off at the 
end angle. The latter could also be enhanced to allow an arbitrary start angle 
of the pies to draw (not necessarily at the start angle of the pie chart).

Animating both start values in different directions would make a cool effect. 
Additionally one could implement kinda zoom feature in the sense that you 
scroll out (rotate out) large pies and then stretch smaller ones over the 
remaining space.
