convert aura from picture to shader

roxxkatt

so for a long time aura upgrades have been a crappy picture that changes color based on the marines hp.
why not convert aura from picture to a shader which can be integrated into the alien vision?
a shader can produce a large number of effects and factor in other things like proximity, and it offloads processing to the gpu

in fact you could probably also offload the "hive vision" team/parasite outlines into a shader as well, and that could then easily be customized to be differentiated between friend/enemy/teammate/etc and could then be faded based on distance/etc
