title: drawElements vs drawArrays in webgl
body: <p>Does it make any sense to use drawElements instead of drawArrays if I'm not going to share any vertices?</p>
  
  <p>If I understood correctly, with drawElements I have to use multiple drawcalls if the index array exceeds ~65k elements because of the uInt16 limitation of the indexbuffer ( in webgl ).</p>
  
  <p>So could one say as a rule of thumb:</p>
  
  <p>No shared vertices, use drawArrays because its just one big drawCall.</p>
  
  <p>If shared vertices, use drawElements because GPU bandwith could be saved and this would result in better performance than drawArrays also if there are multiple drawcalls required?</p>
