godot is an image manipulation program that runs on the c64... it uses that 
4bpp format so it can work on it without having to take the various 
restrictions of c64 graphics modes into account. that format has no practical 
use besides this - and ofcourse for pretty much all other uses people use the 
native format that you can simply copy to video memory.

atleast for my stuff i can say... that the tools i am using are always tweaked 
for a specific application. the only useful "generic" converters are those 
that convert fullscreen graphics - anything else is almost certainly 
application specific.
