put_sprite() will not be the only function.  5-10 other low-level ones 
will be needed, including put_sprite_fogged.

The drawback of this is that it doesn't let GUIs do optimizations like 
(I think) gui-sdl does with fogged ocean tiles.  The advantage is that 
changes to the drawing code become much easier.  Just look at how easy 
it is now to make changes to the drawing code in tilespec.c - much 
easier than for the stuff that is still in gui-xxx/mapview.
