[RFC] Listening to keyboard in background, RawInput and DInput

[Gabriel Ivăncescu]

Hi Rémi,

I don't know much about the input thing, but do you know what Windows 
does when you Alt-Tab? Does it send Alt release immediately to the 
window, or when you actually release it? (even without focus)

If it's the former, I guess one easy way would be to simply release all 
keys that are pressed when they keyboard is grabbed. Not sure if X11 has 
such a notification facility.

But I'm pretty sure you already looked into this and turned out it's 
more complicated than that. :-)
