If you're going to use TimUtil, then:

	- put your sprites somewhere in the (320,0)-(1023,511) region.
	  the entire left side (0,0)-(319,511) will probably be
	  consumed by your frame buffers.
	- make sure those sprites' upper left corners are aligned on
	  16-pixel boundaries and fit within a texture page.  Otherwise
	  interesting things will happen.
	- position the CLUTs so their leftmost pixel is also aligned
	  on 16-pixel boundaries (on the X axis, Y axis can be anything)
	- make sure there is no overlap
	- one exception on overlap: if the CLUTs are identical, then
	  you can overlap probably without problem.

The CLUT palette sizes are:

	TIM type	Width	Height
	---------------	-------	-------
	4-bit		16	1
	8-bit		256	1
	16-bit		n/a	n/a

I usually throw all my sprites in the upper left area and the CLUTs
in the lower right.

Oh yeah, play around with the CLUTs too---you can accomplish color
cycling with that, too.

- e!
