title: WebGL: detect, when out of memory
body: <p>I am making an app, which needs a lot of GPU memory sometimes (many huge textures). I could make a system, where I keep frequently used textures in GPU memory, and I upload and delete the rest, only when they are needed.</p>
  
  <p>In general, there are always more textures than the GPU memory, and the more memory I can use - the faster my program is. I don't want to restrict myself e.g. to 100 MB or 1 GB of memory, when there could be 4x more memory free to use. But if I try to allocate too much, the browser will kill my program.</p>
  
  <p>I see, that in WebGL, there is no direct way to tell, how much memory is available. What would be your strategy, how to solve such issue? </p>
