// The `GDK_INTERP_NEAREST` mode is the fastest scaling method, but has
// horrible quality when scaling down; `GDK_INTERP_BILINEAR` is the best
// choice if you aren't sure what to choose, it has a good speed/quality
// balance.

// **Note**: Cubic filtering is missing from the list; hyperbolic
// interpolation is just as fast and results in higher quality.
