 From the Solaris platform point of view, XCB is fine with me, as we have
xcb 1.6 on Solaris 11, and no longer update the Mesa version in Solaris 10
(which has no XCB included - those who want to build new versions themselves
  should be able to build xcb for Solaris 10 as well).

Most applications still use libX11, but since we ship the libX11 1.4.x built
on top of libxcb, the standard xcb/xlib handoff calls should work just fine.
