  x11-servers/xwayland-devel: document DRI3 quirk
  
  Wayland clients (unlike server/compositor) are not supposed to require
  special privileges. Something in drm-kmod fails to authorize access to
  /dev/dri/* even if user is under "video" group.
  
  Not a port option because Xwayland doesn't know how to drop priveleges.
  
  Approved by:	ports-secteam blanket (runtime fix, no content changes)

+Known issues:
+- When /dev/dri/card0 and /dev/dri/renderD128 have different major(3)
+  DRI3 may fail e.g., on i915kms in I915_GETPARAM with EACCESS.
+  Without DRI3 for glamor Xwayland falls back to swrast (llvmpipe).
+  If OpenGL applications appear slow check with glxinfo then try
+  enabling setuid bit e.g.,
+
+    $ glxinfo | fgrep Device:
+        Device: llvmpipe (LLVM 8.0, 256 bits) (0xffffffff)
+    $ chmod u+s `which Xwayland`
