	* app/widgets/gimpcellrenderertoggle.c: fixed size calculation,
	removed padding and the spacing between the icon and the frame
	around it.

	* app/widgets/gimpwidgets-utils.[ch]: added gimp_get_icon_size()
	which returns the best matching icon size for a given allocation.

	* app/widgets/gimpcomponenteditor.[ch]: adjust the eye icon's
	size according to the preview_size.

	* app/widgets/gimppreviewrenderer.c
	(gimp_preview_renderer_default_render_stock): use gimp_get_icon_size()

	* app/widgets/gimpcomponenteditor.c
	* app/widgets/gimpcontainertreeview.c: iterate the tree model
	using a for() loop instead of nested if() { do { } while() }
	stuff.
