Have you taken a look at SDL_Image?  That is the library that I use.  I 
don't know what it does.  It might do some
more scuzzy marco hoops.  I hope there are hoops...  I'll do a little 
work tonight.  I'm going to head to work this
week, so I don't know how much sakala hacking there will be.  

I fixed the turn one way, push another way bug.  It turns out ut was 
swaped in two places, in the functions turn-left and
turn right, and in the sprite animation.  D'oh.

You should find out if anyone is hacking out a UFFI interface for openMCL.
