Added symbolic themable colors. Patch is a merged version of proposals

Browse Source 
2005-11-23  Michael Natterer  <mitch@imendio.com>

	Added symbolic themable colors. Patch is a merged version of
	proposals from Matthias and maemo-gtk. Fixes bug #114355.

	* configure.in: require glib >= 2.9.1 for refcountable hashtables.

	* gtk/gtksettings.c: added property "color-scheme" which is a
	string defining colors like "foreground:black\nbackground:grey".
	Automatically provide a name->GdkColor hash table mapping for the
	color scheme.

	* gtk/gtkrc.[ch]: added list of color hashes that works like the
	list of icon factories. Append the color scheme hash from
	GtkSettings if it exists. Extended gtkrc syntax to allow defining
	and referencing of logical colors. Also allow to modulate colors
	in gtkrc by using arbitrary expressions of mix(), shade(),
	lighter() and darker(). Added internal function
	_gtk_rc_style_get_color_hashes().

	* gtk/gtkstyle.[ch]: keep a private list of color hashes around.
	Get the list from _gtk_rc_style_get_color_hashes(). Export
	internal function _gtk_style_shade() (used by above color
	expressions). Added public API gtk_style_lookup_color() which
	looks up a logical color by name.

	* gtk/gtk.symbols: add gtk_style_lookup_color

	* tests/testgtkrc: use symbolic colors for making
	the scrollbars red.
