Provides a mechanism by which applications can customize the window type selection for a given GLCapabilities. Developers can implement this interface and pass an instance into the appropriate method of GLDrawableFactory; the chooser will be called during the OpenGL context creation process. Note that this is only a marker interface; its signature is the same as CapabilitiesChooser and the List of objects extending CapabilitiesImmutable passed to chooseCapabilities is actually a List of type GLCapabilitiesImmutable.
