x11/GLX/GL on top of wayland

Xwayland has DRI3/Present support, which means that any app that uses DRI3
will work fine under it. Right now, this is the Intel driver, with support
for the other FOSS drivers coming soon.

Otherwise, we fall back to non-hardware-accelerated codepaths. It won't
break, but it will mean that you won't get hardware-accelerated rendering.
