12	/* The constant alpha factor describes an alpha factor that gets applied
13	to the result of the composition operation combining it with the destination.
14
15	The intent is that if const_alpha == 0. we get back dest, and if const_alpha == 1.
16	we get the unmodified operation
17
18	result = src op dest
19	dest = result * const_alpha + dest * (1. - const_alpha)
20
21	This means that in the comments below, the first line is the const_alpha==255 case, the
22	second line the general one.
23
24	In the lines below:
25	s == src, sa == alpha(src), sia = 1 - alpha(src)
26	d == dest, da == alpha(dest), dia = 1 - alpha(dest)
27	ca = const_alpha, cia = 1 - const_alpha
28
29	The methods exist in two variants. One where we have a constant source, the other
30	where the source is an array of pixels.
