function panels_renderer_legacy::render in Panels 6.3

Builds inner content, then hands off to layout-specified theme function for final render step.

This is the outermost method in the Panels render pipeline. It calls the inner methods, which return a content array, which is in turn passed to the theme function specified in the layout plugin.

Return value

string Themed & rendered HTML output.
