* testfilechooser.c: Add over-big test case for preview
(much of size from a modified copy of
gdk_pixbuf_new_from_file_at_size())
* gtkfilechooserutils.[ch] gtkfilechooser.c
gtkfilechooserprivate.h gtkfilechooserimpldefault.c:
Add get_preview_path() as a virtual function; implement
update-preview signal that was in the header file.
* gtkfilechooserimpldefault.c: Finish a simple preview
widget implementation.
