All the evidence suggests that layer was the wrong thing to call it. "Level" is the correct term. This goes back as far as the 1983 paper on image pyramids: http://classes.soe.ucsc.edu/cmps160/Fall05/papers/p1-williams.pdf

We should deprecate all the existing functions that reference "layer" and create new ones that use "level". This is important also, because there are some formats that actually have layers, with levels within them.
