Agent position is displayed differently if `scale` is set

[nshlapo]

Agents are typically centered on their position in the xy plane, with the bottom of an agent's bounding box located on the z-coordinate.

However, if height is 0 but scale is non-zero, the agent is fully centered on their position in 3d space.
