- * Accumulation buffer notes
- *
- * Normally, accumulation buffer values are GLshorts with values in
- * [-32767, 32767] which represent floating point colors in [-1, 1],
- * as defined by the OpenGL specification.
- *
- * We optimize for the common case used for full-scene antialiasing:
- *    // start with accum buffer cleared to zero
- *    glAccum(GL_LOAD, w);   // or GL_ACCUM the first image
- *    glAccum(GL_ACCUM, w);
- *    ...
- *    glAccum(GL_ACCUM, w);
- *    glAccum(GL_RETURN, 1.0);
- * That is, we start with an empty accumulation buffer and accumulate
- * n images, each with weight w = 1/n.
- * In this scenario, we can simply store unscaled integer values in
- * the accum buffer instead of scaled integers.  We'll also keep track
- * of the w value so when we do GL_RETURN we simply divide the accumulated
- * values by n (n=1/w).
- * This lets us avoid _many_ int->float->int conversions.
