Avoid GtkStyle-based "paint" functions.

Use GtkStyleContext-based "render" functions instead.

   gtk_paint_arrow()    --> gtk_render_arrow()
   gtk_paint_box()      --> gtk_render_background()
   gtk_paint_expander() --> gtk_render_expander()
   gtk_paint_flat_box() --> gtk_render_background()
   gtk_paint_shadow()   --> gtk_render_frame()
   gtk_paint_vline()    --> gtk_render_line()
