// Get the number of atlases to load into this texture
Texture.prototype.getAtlasCount = function() {
var val = (data.atlasCount / config.atlasesPerTex) > (this.idx + 1)
? config.atlasesPerTex
: data.atlasCount % config.atlasesPerTex;
// handle special case of single atlas that's size of single texture
return val ? val : 1;
}

if data.atlasCount == 16 && config.atlasesPerTex == 16 && this.idx == 0, then val is 16 % 16 ==0 , return 1。but return must be 16。
