Detailed Description

Given a Cairo context, draw a circle. The circle is specified by a central point (x, y) the radius and whether it is filled or not. Assumes that the Cairo context is already configured for line width and colour.

Constructor which draws an arc at a particular location. This constructor also stores the various member variables for radius, angle and fill state.

Parameters

x	The x location to draw use as the center.
y	The y location to draw use as the center.
radiusIn	The radius to draw the arc to.
bool	fillIn Whether the fill or not.
