    //      Add bitmap i;

    // NOTE: if we use the fixed function pipeline to composite
    //      these into the CompositeMaterial, then they all need to
    //      be scaled down to avoid saturation on summation.
    //      Doing the composite with a pixel shader would allow the
    //      textures to be stored in full 256 range, and then scaled
    //      down during the summation, after interpolation. Would
    //      that be better? Not sure. Pixel shader registers only have
    //      a range of [-1..1], and it's hinted to be 8-bit fixed point.
    //      So we'd still have to scale down texture value (losing precision),
    //      then add it in.
    //
    //      Also, for pixel shaded compositing, we can just store the cosine
    //      values in each layer, with no rotation in the bitmap values, just
    //      in the layer transform. No rotation would make for a cleaner
    //      interpolation (not interpolating diagonally across the waves).
    //      How much difference is that? Dunno. But it would also allow the
    //      bitmap to hold the full range [-1..1]=>[0..255] of cosine values,
    //      scaling them down with constants. The pixel shader would look like:
    //
    //          tex     t0;
    //          tex     t1;
    //          tex     t2;

    //          mad     r0, t2_bx2, c2, r0;
    //          mad     r0, t3_bx2, c3, r0;
    //          // Now bias it back into range [0..1] for output.
    //          mad     r0, r0, c4, c5;     // c4 = (0.5, 0.5, 0.5, 1), c5 = (0.5, 0.5, 0.5, 0)
    //          // or add_d2    r0, r0, c0.b; // except this is likely to saturate before the divide. Dunno.
    //
    //      where the c[i] constants would be:
    //          c[i] = -wave[i].amp * wave[i].freq * kSomeNormHack * (wave[i].fDir.x, wave[i].fDir.y, 0, 1)
    //      except c[0].b = 0.7;
    //      In fact, we could cut it down to 2 textures using alpha replicate, except we need different
    //      transforms for each (for animation). So screw that.
    //
    //      Note that the above won't run on a ps.1.0 pixel shader, because the combined number of tex and
    //      arith instructions is 9. Could make a version that was okay for ps.1.0 by doing:
    //
    //      mad     r0, t0_bias, c0, c4; // t0[-0.5..0.5]*c0 + 0.5, which is [0..1]

    //      mad     r0, t3_bias, c3, r0; // + t3[-0.5..0.5]*c3
    //
