Kevin Ballard:
	- Anchor the item tooltip intelligently
	Put the item tooltip on whichever side of the row has more room instead
	of always trying to put it on top of the row.
	- Tweak how lines are laid out
	Instead of using spaces to pad out each line, change the point of the
	line such that it doesn't start until the text does. This prevents
	mouseover in the padding from showing the tooltip.
