How far back from the edge a leap may be launched. Measured against the simulator: a jump that
clears a gap leaves the ground anywhere from just over half a tile before the lip to a little
past it, so the window is anchored to the lip rather than to the tile's centre - a diagonal
leap's lip is 0.707 out from the centre, not 0.5, and launching at the centre wastes most of
the jump's reach before the gap even starts.
