SilentSpike b6dd7b941f Reduce overhead of spectator map icons
Fixes #2514 by only rendering individual unit icons when zoomed in and only rendering the units currently within the screen bounds.

Behaves as expected, but whether or not it has a significant performance increase under scaled up testing conditions remains to be seen.
