float TreeMapSquaredLayout::GetNormAspect	(	float	big,
		float	smal,
		float	a,
		float	b
	)			const

Calculate normalized aspect ratio.

Parameters:

	big	Bigger side of the node rectangle.
	small	Smaller side of the node rectangle.
	a	Weight calculated from the size of the node.
	b	Weight calculated from the size of the node.

void TreeMapSquaredLayout::UpdateLayout	(	TreeMapItem *	item,
		LayoutRectangle	rc
	)			[virtual]
