From 7ae1aa6b374aa86d70638e38b0fe6abdbb832475 Mon Sep 17 00:00:00 2001 From: Marco Date: Wed, 15 Jul 2015 18:00:03 -0700 Subject: [PATCH] Dynamic resize for 1 pass: update of golden frame. In aq-mode=3 under a resizing action (i.e., resize_pending != 0), force an update of the golden reference frame.
