Thu Jul 15 22:19:40 2004  Matthias Clasen  <maclas@gmx.de>

	Fix #60128, #58307, #144706:

	* gtk/gtkstyle.c (gtk_style_real_copy): Handle references
	to bg_pixmaps properly.
	(gtk_style_real_unrealize): Don't keep dangling references
	to the bg_pixmaps.
	(gtk_style_attach): Split the loop into two loops, first
	looking for a matching style, then for an empty one.
	(gtk_style_finalize):
	(gtk_style_duplicate): Add comments explaining the handling
	of style->styles.
