libxcb: libxcb 1.12 (X11 interface library)  
libxcb:  
libxcb: The libxcb package provides an interface to the X Window System 
libxcb: protocol, which replaces the current Xlib interface. Xlib can also use 
libxcb: XCB as a transport layer, allowing software to make requests and 
libxcb: receive responses with both.
