Didn't realize Cacio was so well-suited for multi-screen environments,
I now simply create seperate screens and GraphicsConfigurations. Works
really well, even when rendering is triggered by non-input threads :)

Glad you like it - however many features are still missing, I'll have
to do some clean-up before I'll release it in the wild.

I got mouse-events mostly working (same state as the SDL backend),
however key-events remain a mystery.
Even the X11 backend doesn't seem to implement key-events.

Is there some support in Cacio for synthetisizing events?
I read a few comments about it, but didn't find code doing it.

sythetisize the clicked myself I suddenly can click buttons and
checkboxes. However keeping double-clicking etc in mind, I fear this
will be quite tiresome.


Thanks, Clemens
