  Interface design for user-defined name hashing.
  
  1) We use BuiltInResources to pass the hash function to
     ANGLE, deciding whether we applies hash function or not.
  2) We use 64 bits hashing function, because 64 bits is 16
     bytes using hex representation, plus the "webgl_" prefix,
     we can keep the names under 128 (WebGL allows 5 levels of
     nesting in structures).  If chooseing 128 bits, we will
     go beyond 128 characters, and some drivers can't handle
     that safely.
