Texture sRGB issues

[AsherGlick]

When a texture is first rendered in 3D it is forced to be sRGB. This causes issues when the same texture is being used for 2D and for 3D. We should have two instances of each texture loaded, one that can be in sRGB for 3D and one that can be in standard RBG for 2D.

Maybe there is a cleaner fix for this where both 2D and 3D can use the same texture but I am not aware of it.

This can probably be easily implemented alongside #18
