What's JUCE_USE_XRENDER is for?

[nicolasdanet]

The only info i get on this forum is another question from Jules.

XRender?

Just cleaning up some linux code, I spotted the stuff that uses libxrender, apparently to enable transparent windows. But I’m a bit confused - even with it disabled, window transparency works perfectly well! Does anyone know if it’s just a legacy library that’s no longer needed…? Does anyone actually enable the JUCE_USE_XRENDER flag? Are there some situations where it’s the only way to get transparency?

It is set off by default. Is there any reason to use it?
