[evolution-data-server/gnome-3-6] G_PRIORITY_HIGH_IDLE is sufficient to beat GTK+ redraws.

[Matthew Barnes <mbarnes src gnome org>]

commit 147c817dd31ddee0ee097aa58ac3489c4d918f64
Author: Matthew Barnes <mbarnes redhat com>

    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 820dcf6cfc43265c6376f15d983381c3087a5d20)
