a bit shift once to the left is equal to muliplying by 2, only faster. so if you bit shift 4 to the left, it's *2*2*2*2, or, *16. In other words, 4 << 3 = 4*2*2*2 = 32

I'm trying to remember where I read this and how it is applied.

When trying to calculate the position offset for blitting tiles, someone suggested bitshifting the values because they're faster than multiplies. I can neither remember who wrote this, or what it was about. Anyone remember which of the original Iso tutorials/articles this was from and what it was about?
