Texture mipmaps

[TattieBoJangle]

Would it be possible to have a texture mipmap override perhaps in the scene settings I know you can now do it in each texture but it sure would be nice to have a master slider or value to change them all at once

hmm.. toughie that one as they are related to each material now.

It could always run through each datablock and edit the values based on a scene one, but it would require to save all those materials also. Need a think on this one
