use the preview widget here
2002-02-14 Havoc Pennington <hp@pobox.com> * src/theme-viewer.c: use the preview widget here * src/preview-widget.h, src/preview-widget.c: make the theme preview into a nice widget * src/frames.c (meta_frames_ensure_layout): replace frame layout if the frame style changes, this only ends up mattering if you e.g. changed the font size for windows in a different state such as maximized, which is crack, but the code may as well be correct * src/theme.c (meta_theme_get_frame_style): new function so we can detect an invalid cache of the PangoLayout in a frame
