[Bug]: Token VBL half-ignored when revealing FoW

[kwvanderlinde]

Describe the Bug

If a token has VBL and is dragged then dropped, the Fog of War reveal is done as if the topology was first moved to the final position then vision was calculated at each step.

In a similar scenario, if we instead drag the token and set a waypoint, then Fog of War reveal is done as if the topology remained at the original location.

To Reproduce

1. Drag the default Elf token onto a square grid with vision on. Set if to PC and make sure it has vision.
2. Draw a filled rectangular Wall VBL over the Elf's grid square (use snap-to-grid). The Elf should not be able to see anything since it is in Wall VBL.
3. Edit the Elf token, go to the Topology tab, select the Wall VBL button and Erase Source Topology on Move checkbox and hit Move Topology From Map. All the topology from (2) should now be on the token and it still should not be able to see.
4. Drag the Elf token to the right two squares. Notice that vision is revealed as if the topology was always at the final location, instead of going step-by-step.

Expected Behaviour

Nothing should be revealed for the token since it can't see at any of the steps.
