Gene Z. Ragan 82353c4765 Fixed bug 1836, Description list item icon wrong. 
2000-08-02  Gene Z. Ragan  <gzr@eazel.com>

	Fixed bug 1836, Description list item icon wrong.

	* mime-type-capplet/nautilus-mime-type-capplet.c:
	(populate_mime_list), (gdk_font_get_bold),
	Set up proper and scaled description column icon.

	(capplet_gdk_pixbuf_scale_to_fit):
	New function that scales an gdk-pixbuf to the requested
	width and height.  Copied from libnautilus.
