  gles2: Major renderer optimization. Work in progress!
  
  This moves all the rendering to a command list that is flushed to the GL as
  necessary, making most common activities upload a single vertex buffer per
  frame and dramatically reducing state changes. In pathological cases,
  like Emscripten running on iOS's Safari, performance can go from a dozen
  draw calls killing your performance to 1000 draw calls running smoothly.
  
  This is work in progress, and not ready to ship. Among other things, it has
  a hardcoded array that isn't checked for overflow. But the basic idea is
  sound!
