Benchmark: Optimization function

Script Preparation code:

var layr = 0;
var map = {
  tileWidth: 32,
  tileHeight: 32,
  currentLayer: 0,
  layers: [{data: {width: 18, height: 18}}]
}

function snapToFloor(input, gap, start) {
  if (typeof start === "undefined") { start = 0; }
  if (gap == 0) {
    return input;
  }
  input -= start;
  input = gap * Math.floor(input / gap);
  return start + input;
}

function A(x, y, tileWidth, tileHeight, layr) {
  if (typeof layr === "undefined") {
    layr = map.currentLayer;
  }
  x = snapToFloor(x, tileWidth) / tileWidth;
  y = snapToFloor(y, tileHeight) / tileHeight;
  if (x >= 0 && x < map.layers[layr].width && y >= 0 && y < map.layers[layr].height) {
    return map.layers[layr].data[y][x];
  }
}

function B(x, y, tileWidth, tileHeight, layr) {
  x = snapToFloor(x, tileWidth) / tileWidth;
  y = snapToFloor(y, tileHeight) / tileHeight;
  if (x >= 0 && x < map.layers[layr].width && y >= 0 && y < map.layers[layr].height) {
    return map.layers[layr].data[y][x];
  }
}

function C(x, y, tileWidth, tileHeight, layr) {
  x = snapToFloor(x, tileWidth) / tileWidth;
  y = snapToFloor(y, tileHeight) / tileHeight;
  if (x < map.layers[layr].width && y < map.layers[layr].height) {
    return map.layers[layr].data[y][x];
  }
}
