Improve unit label placement

[pvutov]

• Drop height of unit labels when looking into the distance: https://imgur.com/a/pEKGywc - Since labels of closer units are closer to the model, it gives the impression that the units in the distance are further away
• Seems there is some transparency in the LOD of the bloodhound, but this might just be me getting ahead of myself in this stage of the project - https://imgur.com/a/m4AoxbV

Related issue: we should make it so the labels arent on top of the model when zoomed in really close,
