Central sources of NinePatch Images?

Are there any central spots or collection in the net from created NinePatches?

I think they are real fancy and useful things. Even if you are not a designer this can bring you great benefit and look. But I think it would be great if there would be some collections for this in the internet as they are available for icons. But I didn't found anything useful. Поэтому я спрашиваю вас, знаете ли вы о таких местах или веб-страницах?
