4 bit sprite import - palette issues when importing > 1 sprite

[ljg701]

Hi,

I'm trying to import a range of 4 bit sprites, only 16 colours are in use.

The import routine doesn't seem to identify that the sprites are using the same 16 colours between them, and wants to create a new palette of 16 colours for each sprite.

E.g.
Sprite 1 uses colours 1,2,3,4,5 <- system tries to create a new palette
Sprite 2 uses colours 6,7,8,9,10 <- system tries to create a new palette
Sprite 3 uses colours 11,12,13,14 <- new palette etc

I think the import needs to scan the entire range of sprites being imported, and could then conclude that all the sprites could fit in the same palette.
