 Patching crossByHand and sLevitateOverPit to use a fixed slow speed for
 traversal was surprisingly easy. Looks better than a fast tentacle.

 To stamp out intermittency at all slider levels, I had to go slower than
 anticipated. I got misleading success when I teleported rather than
 playing through or loading a savedgame.

 I remember one literal value that worked when the slider was at max, and
 min, but failed when the slider was somewhere in the middle. I'm guessing
 there's convoluted cycle counting going on.

 > Downside: extra travel time costs a little more stamina.

 The [https://bugs.scummvm.org/ticket/10615#comment:10 mechanism] behind
 the drain is already sapping 1 point at a time. It can't be reduced
 further, and the method is too short to modify.

 The drain is noticeable (~80 points patched vs ~40 points unpatched, down
 from starting at ~225). However stamina loss isn't that big a deal in this
 game.
