/*
    Note about the structure of various headers: they're organized in a more
    complicated way than usual because of the various dependencies which are
    different for different ports. In any case the only public header, i.e. the
    one which can be included directly is wx/dataview.h. It, in turn, includes
    this one to define all the renderer classes.

    We define the base wxDataViewRendererBase class first and then include a
    port-dependent wx/xxx/dvrenderer.h which defines wxDataViewRenderer itself.
    After this we can define wxDataViewRendererCustomBase (and maybe in the
    future base classes for other renderers if the need arises, i.e. if there
    is any non-trivial code or API which it makes sense to keep in common code)
    and include wx/xxx/dvrenderers.h (notice the plural) which defines all the
    rest of the renderer classes.
