Title: Add a "radius" argument to pie drawing functions.

A simple modification for something I wanted to use at work: add a "radius" argument to pie drawing functions.

There are default values ('None') for the new argument, so it can be ignored so as to yield the actual behavior. When "radius" is not 'None', it shall be a scalar which shall scale the pie.

As the supplied example shows, no other parameters of the pie are changed by this argument, so, for instance, the font size of labels may have to be manually adjusted. This is actually intentional.
