Raw Blame History

From fb41f028badb4dfddfc47fb2a1a68c1aa90dcef5 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Adds initial Gtk clipboard support to moz-headless
If build with MOZ_X11 enabled then this now builds the clipboard code taken
from the gtk2 backend. This doesn't provide any embedding API yet to expose
the clipboard.
