Clarify When Sprites Have Multiple Palettes

[behreajj]

Hello,

This is a request for the clarification of Sprite:palettes description. It could indicate 1. that multiple palette support is already in use and 2. when sprites will have multiple palettes, such as when indexed images n001.png, n002.png, n003.png are opened as a sequence.

Thanks for considering. Cheers,
Jeremy
