// The generalized alpha compositing formula, "B OVER A" is:
// C(A,a,B,b) = bB + aA - baA
// where:
//    A = background color value
//    a = background alpha value
//    B = foreground color value
//    b = foreground alpha value
//
// However, we need a general formula for composition based on any type of
// blend operation and not just for 'normal' blending. We want multiplicative,
// additive, etc. blend operations.
//
// The generalized alpha compositing formula w.r.t. a replaceable blending
// function is:
//
// G(A,a,B,b,F) = (a - ab)A + (b - ab)B + abF(A, B)
// 
// Where F is a function of A and B, or F(A,B), that results in another color
// value. For A OVER B blending, we simply use F(A,B) = B. It can be easily 
// shown that the two formulas simplify to the same expression when this F is 
// used.
//
// G can be generalized even further to take a function for the other input
// values. This can be useful if one wishes to implement something like 
// (1 - B) OVER A blending.
//
// In this reality, F(A,B) is really F(A,B,r). The syntax "r = F(A,B)" is
// the same as "F(A,B,r)" where r is essentially an 'out' parameter.
