/** Provides a mechanism by which applications can customize the
window type selection for a given {@link Capabilities}.
Developers can implement this interface and pass an instance into
the method {@link GraphicsConfigurationFactory#chooseGraphicsConfiguration}; the chooser
will be called at window creation time. */

/** Chooses the index (0..available.length - 1) of the {@link
Capabilities} most closely matching the desired one from the
list of all supported. Some of the entries in the
available array may be null; the chooser must
ignore these. The windowSystemRecommendedChoice
parameter may be provided to the chooser by the underlying
window system; if this index is valid, it is recommended, but
not necessarily required, that the chooser select that entry.
Note: this method is called automatically by the
{@link GraphicsConfigurationFactory#chooseGraphicsConfiguration} method
when an instance of this class is passed in to it.
It should generally not be
invoked by users directly, unless it is desired to delegate the
choice to some other CapabilitiesChooser object.
