The Dock Shape page determines the shape and initial size of the Dock.
Shape enables you to choose one of the built-in shapes for your Dock. Currently circlular and
ellipsoid shapes are supported.
Format if set to Constant Number of Items per Circle restricts the number of Dock Items that
will appear on each ring - this is set using the Number of Icons Per Circle control. If set to Maximum Number of Icons per Circle then Circle Dock will fit as many Icons as it can into each
circle ring, bearing in mind the rings' circumference and separation values.
As the various shapes have individual size specifications, separate pages are provided, one for
each supported shape.
