Details:
Changing animation speed to minimum in preferences, move any unit, the unit
go fast to the third hex, teleport back to the second, then walk slowly as
expected but (first hex being the source hex).
There is also tiny jumps between hexes (not counting the first big one). Undo
and redo seems unaffected by these glitches.
A possible fix: in unit_animation.cpp:947 removing the " - 20/speed" (or if
it's needed, maybe just control its value somehow) This kill all these
problems and doesn't seems to break anything else. It also make the whole
move smoother.
>From some debug tests, a low speed make the code skip the loop the first
time. And when using a speed of 0.75, the glitch and the skip of the loop
happen less often but are linked.
