Render gadget by passing content instead of URL?

[Dennis Ju]

Hello,

I was wondering if there was a way to render a gadget by passing a gadget's
XML content instead of passing a URL. Looking through the
GadgetRenderingServlet class, it looks like this isn't doable.

Use case for rendering via the content would be to get a quick preview of
the gadget.

Any thoughts on adding such a feature?  Or is this already possible and am I
just missing it?

Thanks,
Dennis
