I don't know of any, but it could be easily implemented.
Just tell me if you like to know about the different ways
and their pros and contras.

You can't take the output surface of the widget here, to...

...render to it...

...and use it as an input surface later on.
It's much better to store the string somewhere in LiteLabel
and call DrawString() for it each time the button is updated.
If you really want to render the string in advance you should
at least create an offscreen surface for it.
