Subject: G_PRIORITY_HIGH_IDLE is sufficient to beat GTK+ redraws.

GTK+ uses (G_PRIORITY_HIGH_IDLE + 20) for redrawing operations, which is
actually a slightly lower priority than G_PRIORITY_HIGH_IDLE.  Therefore
for our purpose, G_PRIORITY_HIGH_IDLE is sufficient.

(cherry picked from commit 60d1c3054aa60d02c763538d6b1f16d9d6ab6ade)
