* Convert binding index to mask bit. * * Each index represents a single bit on the bit-mask. Because bit-mask only has 32 bits, we make * the 32nd bit share all masks for all bindings higher than 32. Since it is extremely rare to * have more than 32 bindings this will be hit very rarely. The dow

(bindingIndex: number)

 * case is that we will execute binding code more often than necessary. (penalty of performance)
