    Revert "engine: make floor sprites clip a little more like floors"
    
    This reverts commit 81f7c71be52e6f23b526f1b4f534fde47bd9667b.
    
    clipmove() really needs concrete indication of a moving point's starting floor height for this optimization to work correctly, and inferring that ourselves without it being explicitly passed in isn't something that would work.
