NAME

       Jifty::View::Mason::Halo - Class for drawing "halos" around page components

DESCRIPTION

   start_component_hook CONTEXT_OBJECT
       Whenever we start to render a component, check to see if we can draw a halo around the
       component.

       Either way, record halo metadata.

   end_component_hook CONTEXT_OBJECT
       When we're done rendering a component, record how long it took and close off the halo
       "span" if we have one.

   _unrendered_component CONTEXT
       Returns true if we're not currently inside the "Body" section of the webpage OR the
       current component is a subcomponent. (Rendering halos for subcomponents being too "heavy")

   render_component_tree
       Once we're just about to finish rendering our HTML page (just before the "</body"> tag, we
       should call render_component_tree to output all the halo data and metadata.
