Add 'Angle' and 'CDev' as parameter to drawPieGraph()

[GoogleCodeExporter]

Sometimes the rendering of 3D graphics is not perfect.

To solve this problem it is useful to act on two static variables:
'Angle' and 'CDev'.

Instead of changing these values in the library, why not add them as
parameters of the function 'drawPieGraph()'?

Apply the patch to add these new features :-D

My library version : svn rev.25
Operating system   : Debian squeeze amd64
