Texture optimization skips mipmap generation

[BlackMoons]

Hi. It seems when using this program to 'optimize textures' with GPU encoding (I did not test CPU encoding), that mipmap functionality is lost resulting in some bad artifacts when zooming out far.

To be clear, these artifacts are present in vanilla, but not if you use 'graphic settings+' on its default settings (enables mipmapping), a mod commonly used with optimize textures to provide .dds support.

Could you confirm that mipmaps are being generated for mod .dds files?
