title: How can I get all attribute bindings for a program in WebGL?
body: <p>I have a WebGL application in which some attributes are bounded to a program via getAttribLocation and some attributes are bounded to a program via bindAttribLocation.</p>
  
  <p>Is there a way in which I can get a mapping of all string names to attrib indices/values for a program? Also, at which point can I do this? I think getAttribLocation can be called after a program is linked, right?</p>
