Excellent :)

It needs to be part of a separate library, as we don't want libQtGui or 
libQtWidgets to link to X11-specific libraries (the choice between the 
wayland, xcb, directfb, kms, etc platform plugins is made at run-time). 
I believe there's an equivalent for Cocoa or Windows already, but I'm 
not sure where it lives or whether it was named support or helpers.

I'm guessing we would have had that already then instead of having an 
X11 only API, but I'm not sure.
