C# Class Pinta.ImageManipulation.UnaryPixelOperations.SetAlphaChannelOp

Specialization of SetChannel that sets the alpha channel.

This class depends on the system being litte-endian with the alpha channel occupying the 8 most-significant-bits of a ColorBgra instance. By the way, we use addition instead of bitwise-OR because an addition can be perform very fast (0.5 cycles) on a Pentium 4.
