	Patch from Bill Haneman (with many modifications) to make
	the focus color work on dark themes and to make the
	focus line width configurable. (#61079, #63074)

        * gtk/gtkwidget.c: Add style properties,
	::focus-widget, ::focus-line-width, and ::focus-padding.

	* gtk/gtkstyle.[ch]: Make gtk_paint_focus() take a
	state argument as well so we can use fg[STATE] to
	draw instead of always drawing with black.
	Cange paint_focus() to respect GtkWidget::focus-width
	and GtkWidget::focus-line-pattern. Fix continuity
	problem where the default 1-1 stipple had a blob
	in one corner and a gap in the other. Change the
	interpretation of x/y/width/height to be the bounding
	box of the focus rect instead of the rectangle
	passed to gdk_draw_rectangle.

	* gtk/gtkcheckbutton.c gtk/gtklistitem.c gtk/gtknotebook.c
	gtk/gtkoptionmenu.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c
	gtk/gtktextview.c gtk/gtktreeview.c: Handle ::focus-width
	and ::focus-line-padding.

	* gtk/gtkentry.c: Handle :;focus-width property; cleanup
	and remove duplicated code; fix drawing of focus rectangle
	when interior-focus = FALSE. (#63072, #63073)

	* gtk/gtkrange.c gtk/gtktext.c gtk/gtktreeitem.c
	gtk/gtktreeviewcolumn.c: Basic fixups to make compile;
	Range and TreeViewColumn will need more extensive fixing.

	* gtk/gtkcolorsel.c: Honor focus line attributes when
	drawing the focus on the color swatches. (#63071)

	* gtk/gtkhsv.c: Honor focus line attributes when
	drawing the focus for the ring and triangle.

	* docs/widget_geometry.txt: Start at documenting how
	various widgets are drawn.

	* gtk/gtkbutton.c (_gtk_button_paint): Export
	_gtk_button_paint() librarywide, so we don't have
	duplicate a bunch of code in gtktogglebutton.c.

	* gtk/gtktogglebutton.c: Use _gtk_button_paint().
