title: How much WebGL memory is available? What happens when I run out?
body: <p>GPU memory is limited -- typically more limited than JS heap sizes, etc. Thing like lots of high resolution images can fill up the memory, and it is a shared resource, so other applications could be using a lot of it up.</p>
  
  <p>In OpenGL, I can query for available memory.</p>
  
  <p>Is there any way in WebGL do the same? How can I tell if I run out? What will happen if I do?</p>
  
  <p>I'm not sure how to manage the experience for WebGL. I can fall back to SVGs or Canvas if necessary, but I don't know when that is necessary.</p>
