Detailed Description

Structure that packs FHashedMaterialParameterInfo plus a "HashNext" value into 16 bytes to save memory. Allows key/value pairs of 16-byte aligned items like vectors to fit in 32 bytes, rather 48, saving significant space on padding. This introduces limitations that Index cannot exceed 32767, and a given material can't have more than 16384 named parameters of a given type. Both of those numbers are at least a couple orders of magnitude larger than seen in practice.
