spriting logic: color palette

[GoogleCodeExporter]

It's best to combine images that share colors so the sprite can stay under
255 colors. Might have to do this in CoolRunnings.

Another thing that should reduce file-size is having the option to generate 
PNG-8
files instead of PNG-24. - Maybe you can make it by default when all images 
doesn't
have 8-bit transparency. - You could even combine images that have 8-bit 
transparency
and the ones that doesn't.

PS: If you drag images from different color ranges to the same sprite it should
change the output file to PNG-24 if the number of colors exceed 256 and maybe 
alert
the user that this is going to happen.

This tool is definitely useful and really cool. Thanks for sharing and Keep the 
good
work!

re:comment 1:

From the PNG perspective, the transparency palette chunk can have as few 
entries as
there are translucent colors--anywhere from 1 to 255--so it should be possible 
to
combine transparent palette images with non-transparent images with really 
minor size
increase.

Even in IE 6, adding transparency at one end of a palette shouldn't impact the
display of opaque images in the same sprite.
