// Optimisation - pack the second UVs into a single short (they could actually go in a BYTE), which frees up a short to store the x offset for this chunk in the vertex itself.
// This means that when rendering chunks, we don't need to update the vertex constants that specify the location for a chunk, when only the x offset has changed.
