+*Note:* 1.7 maintains backwards compatibility with 1.6. The resultant 1.7 slpk will be larger in size than the input slpk. This is due to the creation of Draco-compressed geometries and DXT-compressed textures.  All of these features are important for increased performance. If output slpk size is a limiting factor, the `-x` option can be used to skip writing DXT textures, but this may result in slower drawing performance.
