Well, I think that it would be useful to have an included sprite routine in CrASH, but there are so many different routines out there that have different features. A programmer usually just picks the one that serves his/her purposes best. Creating a good general purpose sprite routine is a hard thing to do. Some people only need a raw 8 by 8 spriteput routine. Others may need an 8 by x, x by 8, or x by x routine. Some may need clipping or masking too. What would be useful is a standard graphics library, but I'm not sure we could all agree on that.
