// Possibilities: | |
// * MD5Digest of {obj,stwRandom} | |
// * CRC32 of {obj,stwRandom} or any linear-feedback shift register function. | |
// * A DES- or AES-style SBox[] mechanism | |
// * One of the Phi-based schemes, such as: | |
// 2654435761 = 2^32 * Phi (golden ratio) | |
// HashCodeValue = ((uintptr_t(obj) >> 3) * 2654435761) ^ GVars.stwRandom ; | |
// * A variation of Marsaglia's shift-xor RNG scheme. |
