2002-02-09  Havoc Pennington  <hp@pobox.com>

	* src/theme-parser.c: try to make more error message strings the
	same, easier for translators

	* src/theme.c (meta_draw_op_free): free color spec for line op
	(meta_theme_free): free the integer_constants hash

	* src/theme-parser.c (parse_boolean): move above first use

	* src/theme-viewer.c: fixes for theme.h changes

	* src/frames.c (queue_recalc_func): don't recreate layout
	immediately, just save title text. should speed things up.
	(meta_frames_set_title): just remove the layout here also,
	and save title text.

	* src/theme-parser.c (parse_toplevel_element): parse title_scale
	attribute on frame_geometry

	* src/theme.c: support setting the text size

	* src/frames.c: support setting the text size

	* theme-format.txt: updates
