From what I've seen PNG gives BETTER compression than GIF for flat shaded
ldlite type images, and as far as I can tell it only does 32bpp true color.
I put a sample PNG on the ldglite web page if you want to try converting
to various formats to compare sizes.
No need to look into BMP since I already have that working (although it's
just the uncompressed 24bpp style like from ldlite).
By the way, where do I get ImageMagic?
