scalos use won routines.The iconlib you can install or not depend on you.
In the install archive is a FAQ.a A4000 030 can run AFA but you must use a truecolor Workbench screen for new iconlib.If you dont want truecolor screen on WB then you can remove icononlib.
png icons are zlib compressed by default.But when you have a paint program that let you choose the PNG compression you can save png uncompressed.maybe thats better for speed on a 030
