Rich text editor in components

[Carlos]

I mean a function that just returns the component as a string, unprocessed. Just like I18N's return_i18n_component.

Components can be used for other things, not only php scripts. Or you can have some component to be processed by a plugin, not just by get_component. (In fact some of mvleck's plugins do it -for custom rendering-, but I suppose they the above mentioned function to get the component content.)
