pub const NEAREST_MIPMAP_LINEAR: TextureMipmapFilter = TextureMipmapFilter::MipmapFilter{criterion: TextureFilter::Nearest,
                                  mipmap: TextureFilter::Linear,}

When texturing a pixel, select the two mipmaps that are nearest in size to the pixel, select the texel in each that is closest to the center of the pixel, and compute the result by taking the weighted average of each texel.
