/*
	Graphics general concepts:
	Each display element shown is based on a ClusterElement.
	We maintain a vector of elements to be drawn. The list is kept in z-order.
	The lowest order element is the background element.

	ClusterElements can draw to their own framebuffers, or directly to the screen (which
	may be double buffered itself.) Wherever possible, it is best to pre-render elements
	to framebuffers that can quickly be copied to the screen using DMA or BitBlits.
	The mBackgrond element is an example of this. It draws a gradient at boot time, and then
	never has to recreate the gradient again. It can simply copy the rendered image from its
	framebuffer to the screen.

	ClusterElements keep track of their foreground and background regions that need repainting
	using the Region class. The drawing cycle consists of two phases:

	Phase 1 Update() : 
		During the update phase, ClusterElements determine what state changes have occurred since
		the last Update/Draw cycle. If their internal elements have moved, they may have exposed 
		an area from the element below it. This is indicated by returning a Region object from
		the Update() call. The Update() phase is called in reverse z-order. So, the top elements
		are updated first. Since each object returns a region of what it exposed, the next element
		called will be passed the Region that was just invalidated. If this next element called
		can completely draw the exposed area, it will n
