//: Component Style interface.
//- !group=GUI/Framework!
//- !header=gui.h!
//- <p>The component style class is part of the style customization system of the
//- GUI. Each 'style' for a component is implemented by inheriating
//- CL_ComponentStyle and then attaching it to the component it is responsible
//- of visualizing.</p>
//- <p>When a component is constructed, it will contact its CL_StyleManager and
//- ask it to attach the component styles for its style to the component.
//- The general principle in the component style system is that a inheriated
//- CL_ComponentStyle object will hook itself into signals in the component it
//- is visualizing, thus keeping a kind of document/view relationship with its
//- component.</p>
//- <p>For source examples of how this is done, have a look at the GUIGL example.</p>
