	* notebook.tcl: Added an extra check to move the leftmost tab a
	touch to the right when it is not selected (again, to make the
	tabs more Windows-like).  Also replaced redundant [string equal]
	checks with a stored pre-check (ie, set foo [string equal ...]).

	* notebook.tcl: Changed appearance of tabs; leftmost tab is now 
	flush with the left of the notebook, and the tabs look more
	Windows-like.

	* dialog.tcl: Added a new parameter to the draw procedure that
	allows me to pass in the desired geometry for the window. This was
	needed to support tracking of dialog window geometries.

	* tree.tcl: Changed the <KeyPress-space> binding to use "+", so it
