Aquarium normal maps load in a different way depending on browser (artifacts on MS Edge)

[Oletus]

It seems as if color space handling of loaded images differs between MS Edge and other browsers. This causes normal maps to be distorted on MS Edge. The fix for this according to the spec would be setting UNPACK_COLORSPACE_CONVERSION_WEBGL to NONE, but unfortunately MS Edge doesn't implement that at the moment. Another possible fix would be to decode the normal map PNG files in JS.

Edge needs to support the spec. We should not be catering to their lack of actual WebGL support IMO.

That's reasonable - setting UNPACK_COLORSPACE_CONVERSION_WEBGL still needs to be added to tdl once Edge is fixed.
