from the original theme renderer's template.pt (associated to the
cpsskins skin). It gets propagated all the way from the view to the
portlet, through the page, cells, etc. as a keyword parameter that the
renderer can use at any time.

the orginal context is also propagated.

cf. in

    <body tal:content="structure python:pageview(
      engine='default')" />

yes, CPSSkins was created from the beginning as a simple replacement of
main_template before all the theme / page distinctions were introduced.

the breakthrough difference in the zope3 version is that the main
content area (inside the O wrap) can be rendered directly in python.

yes, these would be application-specific portlets, as the ones used in a
calendar application for instance showing a monthly agenda. The portlet
gets access to the current view object, to the current page location
(renamed from 'context_obj' to 'location'). So as soon as you can
produce some data from that you have a portlet that can be put inside a
theme page.

it is not recommended to render portlets directly in HTML though (except
for the main content portlet), since cpsskins takes care of formatting
and displaying the data using widgets.
