Create a system for rendering one or more single sprites.
This system should be able to enable and disable any number of sprites (provided system maximum).
It should be possible to set the graphic to use for a sprite, its color palette entry, and its X,Y position.
It's likely shadow sprite data will need to be reserved in BSS / RAM, to where the PPU sprite RAM DMA can be used.
A stack or counter to indicate the next available sprite should be engineered.
