Issue Context
Placing too many signs in one area and applying the 'glow-ink sac' to the signs will cause significant frame-rate drops. This issue was encountered on a test world containing multiple signs explaining different components of different systems, before signs were changed to the brighter font, frame rates were stable. Roughly 30 signs were in the area.

Steps to Reproduce

1. Place numerous signs in one area containing any form of text.
2. Use 'glow-ink sac' on all the signs placed in the area.
