/*
Let U be 'up', D be 'down' and M be 'multiplied' (the result), and suppose for the moment
that pixels are both NOT premultiplied and normalized to [0, 1].
The additional value v is used to add to RGB components of the U pixel:
U'_rgb = (U_rgb + v / 255)
The matte component is either U_m D_m in case (matte == true), or D_m in case (matte == false).
Please, observe that in the case (matte == false) that choice makes the product NOT COMMUTATIVE,
but I think that's justified - it's simply the most obvious use case.
In case (matte == true), each channel is multiplied independently, and that's it.
The matter is more complicated when (matte == false). The problem in this case is dealing with rgb
components when U and D both have some transparency. When U is fully transparent, we expect the
result to be D, and vice-versa, which is non-trivial.
We REQUIRE that (let's denote r only here):
M_r = M_r_u = U_r (1 - D_m) + U_r D_r D_m, when U_m == 1 (When U is fully opaque, M_r is a D_m-linear
combination of U_r and U_r D_r)
M_r = M_r_d = D_r (1 - U_m) + U_r D_r U_m, when D_m == 1 (Vice-versa, when it's D that is fully opaque)
Finally, we're building a weighted sum, by U_m and D_m of the two above:
M_r = (M_r_u * U_m + M_r_d * D_m) / (U_m + D_m) =
= (...) =
= [ U_r U_m (1 - D_m) + D_r D_m (1 - U_m) + 2 U_r U_m D_r D_m ] / (U_m + D_m)
