Owen Taylor 2d372c4053 Add an extra parameter use_text to gtk_paint_label() to deal with
Mon Apr 30 19:18:07 2001  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkstyle.[ch] gtk/gtkaccellabel.c gtk/gtkcellrenderertext.c
	  gtk/gtkhruler.c gtk/gtkhscale.c gtk/gtklabel.c gtk/gtkprogressbar.c
	  gtk/gtkvruler.c gtk/gtkvscale.c: Add an extra parameter
          use_text to gtk_paint_label() to deal with style->bg[] vs style->text[].

	* gtk/gtkbbox.c gtk/gtkdialog.c: Tweak padding some to deal
	  with GtkWidget::interior_focus = TRUE better.

	* gtk/gtkbutton.c

	* gtk/gtkwidget.c (gtk_widget_style_get_valist): Remove
	G_VALUE_NO_COPY_CONTENTS, to correspond with the recent
	change that had to be made with g_object_get.
