angif layered

fork of Phil Howards Angif 1.0.0 beta3 (http://freecode.com/projects/angif)

Implemented "layered" (usage of transparency) 24bit color-depth support for gif instead of the original tiled one (mosaic of 255 color gifs). Instead of the divide-and-conquer approach this one uses sorting (bubble sort, sorry) for color frequency and distance grouping.

Build as windows command line tool with MingGW.

Workflow: import truecolor image to GIMP, export 24RAW from GIMP, feeding to rawtogif.exe e.g. "rawtogif.exe 1024 768 sunflower.raw"

output a uncompressed (no LZW compression) GIF, needs to be feed to gifsicle for reasonable size.
