\class BasicFill BasicFill.h "vcf/GraphicsKit/BasicFill.h"
This class is a basic implementation of the Fill interface. It is suitable for 
rendering a solid color fill with optional alpha and anti-aliasing support.
If anti-aliasing is turned on then an attempt will be made to render the
fill using <a href="http://www.antigrain.com/">AGG</a>, assuming a render
buffer for the GraphicsContext is available. Alpha support is only used if 
the rendering is performed by AGG, otherwise it is ignored.
