/**
 * Loader for KTX 2.0 GPU Texture containers.
 *
 * KTX 2.0 is a container format for various GPU texture formats. The loader
 * supports Basis Universal GPU textures, which can be quickly transcoded to
 * a wide variety of GPU texture compression formats. While KTX 2.0 also allows
 * other hardware-specific formats, this loader does not yet parse them.
