// 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;
// tex t3;
//
// mul r0, t0_bx2, c0;
// mad r0, t1_bx2, c1, r0;
// 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, t1_bias, c1, r0; // + t1[-0.5..0.5]*c1
// mad r0, t2_bias, c2, r0; // + t2[-0.5..0.5]*c2
// mad r0, t3_bias, c3, r0; // + t3[-0.5..0.5]*c3
