    // A surfer boy in the beach, disney/pixar style. I had to be very careful
    // with the complexity, otherwise the browser would crash during shader
    // compilation. I also had to split the boy in two layers because of that,
    // see below (the single pass version is smaller of course but takes 3 extra
    // seconds to compile, and renders a bit more slowly)
    //
    // This is totally painted to camera, it won't work from others perspectives.
    //
    // Common   - contains some basic stuff
    // Buffer A - renders the brackground - not super polished really
    // Buffer B - blurs the background
    // Buffer C - paints the boy, except the hand and the board
    // Image    - paints the hand and the board, and does some minimal postpro
    //
    // If you have a slow PC, you can watch it here:

    // An animation test - a happy and blobby creature jumping and
    // looking around. It gets off-model very often, but it looks
    // good enough I think.
