A CSprite is an ordered list of these elements, created with <CTRL-r>.  Normally, they are packed together in a list and the 
address of the first is passed to routines.

See ::/Demo/Graphics/SpritePlot.ZC, ::/Demo/Graphics/SpritePlot3D.ZC, ::/Demo/Graphics/SpritePut.ZC, 
::/Demo/Graphics/SpriteRaw.ZC and SpriteMeshEd().

Be aware that copying SP, IB, or IS entries with the clip results in duplicate entries with different nums.  You can manually 
remove dups by editing with <CTRL-t> and setting to the original num.

See ::/System/Gr/GrSpritePlot.ZC for how CSprite are stored.
