title: Merge 2 images with node.js?
body: <p>I want to merge 2 images using node.js. Or rather, i want to place one smaller image on cordinates x,y on a larger image. 
  Even more precise: I have an image of glasses, and an image of a face and i want to put the glasses on the face. 
  I did some googling, and found some image manipulating libraries, but none seem to be able to merge images.</p>
