Hi! (To Ian - I subscribed you to this list that deals with technical details. Since you're a bit involved in the animation technology you should probably receive these mails too.)
I removed the nw and sw animations from the cvs, since the latest version reuses the ne and se animations by flipping them. Moreover, I shrank the remaining sprites to half size and trimmed them to save some space. A "cvs update" should remove the unnecessary sprites and update the remaining ones as well as the Windows executable.
