[gnome-shell] Improve handling of gradients

[Florian Müllner <fmuellner src gnome org>]

commit fd1ce40ee7e5eb389cfaecaf4d56f86ae781da89
Author: Florian Müllner <fmuellner src gnome org>
Date:   Wed Feb 3 21:30:35 2010 +0100

    Improve handling of gradients
    
    By calling clutter_actor_get_allocation() in st_widget_recompute_style()
    to determine whether to redraw gradients, we triggered a complete
    reallocation of the stage for each gradient.
    
    As gradients are processed in st_widget_real_style_changed() anyway, the
    additional checks in st_widget_recompute_style() are redundant and can
    be removed altogether.
