impeller::MipFilter::kLinear
@ kLinear
Sample from the two nearest mip levels and linearly interpolate.
impeller::MipFilter::kBase
@ kBase
The texture is sampled as if it only had a single mipmap level.
impeller::MinMagFilter::kNearest
@ kNearest
Select nearest to the sample point. Most widely supported.
