990707	Rudegrid widget: make sure that the x/y_layout resources
	are allocated before XtFreeing them.

990703	Rudegrid widget: do not try to layout children whose
	core.managed resource is False.

990702	Another widget: Tooltip, which displays tooltips. The code is
	essentially the same as the one previously in tooltip.c,
	which has been removed.
	Yet another: Handle, which can be used to detach a widget from its
	parent by reparenting its window. The widget can then be moved
	around using the handle. Double-click to reconnect.

990701	New SiagMenuButton widget, which is identical to the one in Xaw3d
	but uses XTranslateCoordinates rather than XtTranslateCoords.
	This is to get coordinates right when menus are undocked.
	Changed Combo widget and tooltips in the same way. Should really
	try to figure out what is wrong in the first place...

981130	Sanity tests for family, fg and bg in encode_format and
	decode_format.

981126	Press any key to pop down combo boxes without selecting.

981126	Background colours in Table widget.

981120	PS font selection was broken for fonts that should have Latin1
	encoding.

981104	Hsep and Vsep widgets removed. The same job can be done by
	a thin Label (height or width = 2) with no text.

981102	New Combo widget. Currently the widget only handles geometry
	management for a Textfield widget and a Command widget.

981016	Replaced my Textentry widget with Rob McMullen's TextField widget.
