[gtk+/treeview-style: 1/8] Make GtkCellArea use GtkStyleContext

[Carlos Garnacho <carlosg src gnome org>]

commit 9b2e297977f982cb3e3ced105e77e8b8d1446e19
Author: Carlos Garnacho <carlosg gnome org>
Date:   Wed Jan 12 21:07:05 2011 +0100

    Make GtkCellArea use GtkStyleContext
    
    gtk_cell_area_[gs]et_style_detail() is no longer needed, as
    the passed widget's context would already have all necessary
    info.
