Right, thats a good point. Would tex.setCompression(OF_COMPRESS_NONE) disable mipmaps?
Atleast thats what I'm kind of getting from the description here, though it sounds a bit weird..

E: nvm there is a disableMipmap() function (https://github.com/openframeworks/openFrameworks/blob/master/libs/openFrameworks/gl/ofTexture.cpp#L928)
