'''In some contexts, computing m_isShowable can be a performance
problem. For example, when showing fields of some object on layout
"buttons", there are plenty of fields that simply can't be shown on
this kind of layout: it is no worth computing m_isShowable for those
fields. m_isRenderable is meant to define light conditions to
determine, before calling m_isShowable, if some field has a chance to
be shown or not.
In other words, m_isRenderable defines a "structural" condition,
independent of any object, while m_isShowable defines a contextual
condition, depending on some object.'''
