That's an interesting question, since I suppose the text plugin (which
handles the drawing of the text for all switchers except
staticswitcher and the normal switcher) wasn't really written with
this in mind.

I imagine the end-goal here would probably be to find out when a
switcher intends to display text and then emit a signal of some sort
using d-bus.

I initially thought you could probably hook into the function where
text is rendered[1], but I don't know if that's exactly what you want.
Plugins can pre-render the texture containing the text at any time,
but its up to them to draw it on-screen.

That said, I'm sure they all follow the same logic. Perhaps its a
candidate for refactoring into a utility function in the text plugin,
which can also emit such a signal?

Sam.
