title: Vector drawables that are automatically converted to pngs
body: <p>At Google IO, the Tools team briefly showed the possibility to define vector drawables with a specific suffix (e.g. ic_heart_<strong>48px</strong>.xml) that will then be converted to pngs of all necessary densities. Unfortunately I don't find any documentation about this feature besides the IO recordings.</p>
  
  <p>Is this a feature of the Build Tools or of Android Studio? Assuming it's part of the Build Tools, is it available already? Which version should I be using? Do I have to enable the feature explicitly?</p>
  
  <p>Does Google provide its material icons in the Android xml vector format?</p>
