anybody with more insight into transparentResolvers (matej, igor?):
what is the desired behavior for invisible transparentResolvers?
it's really undefined right now, as the resolver is not rendered, but the
"children" _are_ (though without markup).
if "children" of an invisible transparentResolver should be rendered, i may
have an easy fix for this in Component#render(MarkupStream):
instead of
if (isRenderAllowed() && isVisible()) ....
we could do
if (isRenderAllowed() &&
(isVisible() || (this instanceof MarkupContainer &&
((MarkupContainer)this).isTransparentResolver())))
nevertheless i think that the expected behavior of setting a
transparentResolver to invisible is that it's "children" are not rendered.
