From 2051514652481a83bd7cf22e57cb0fcd40333f33 Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Wed, 10 Sep 2014 14:02:13 -0700 Subject: present: Support PresentOptionCopy We added this option to the present protocol before 1.0 but somehow never implemented it in the server. It's pretty simple; just don't ever do flips if the application specifies Copy.
