Havoc Pennington 1b3c921437 Handle case where we need to parse the xsetting as if it were an RC file 
2001-05-10  Havoc Pennington  <hp@redhat.com>

	* gtk/gtksettings.c (gtk_settings_get_property): Handle case where
	we need to parse the xsetting as if it were an RC file string.

	* gtk/gtkcolorsel.c (gtk_color_selection_class_init): load initial
	value of palette from settings, not from static variable

	* gdk/x11/gdkevents-x11.c: add color palette, toolbar mode to
	xsettings translation table

	* gtk/gtktoolbar.c (gtk_toolbar_new): Remove arguments, because
	hardcoding the toolbar style conflicts with new customizable
	toolbar style philosophy
	(gtk_toolbar_class_init): add settings for default toolbar style;
	these are used unless the app specifically forces a toolbar style

	* gtk/gtksettings.c (settings_install_property_parser): only
	return at the start if we warn and parser == NULL

	* gtk/gtkcolorsel.c (gtk_color_selection_finalize): disconnect the
	palette changed handler so we don't notify dead color selections

	* gtk/gtkstyle.c (gtk_default_draw_shadow): handle
	xthickness/ythickness of 0 or 1 properly
	(gtk_default_draw_resize_grip): clear the background behind the
	resize grips, and align to bottom right if we square the
	area to be drawn.

	* gtk/gtkstatusbar.c (gtk_statusbar_init): set horizontal usize on
	statusbar label to 1, so it doesn't make toplevels resize oddly
	(gtk_statusbar_size_request): add grip size to request
	(gtk_statusbar_size_allocate): hack so the hbox still works with
	the grip size in the request

	* gtk/gtktoolbar.c (gtk_toolbar_show_all): override to fix
	bug where showing all on a toplevel makes the toolbar
	button text appear despite the toolbar mode

	* gtk/gtkmenubar.c: add internal padding style property

	* gtk/gtktoolbar.c: Add internal padding style property; add
	shadow type style property

	* gtk/gtkmenubar.c (gtk_menu_bar_paint): paint box with widget
	state; and put Container::border_width outside the frame

	* gtk/gtktextview.c: don't draw focus rectangle if we're in
	interior focus mode, we just use blinking cursor
