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.
