SetAlpha
Function
This is simply a macro for Set and Crop that sets the alpha
to 1 by default. The reason it exists is that in the Infinite Workspace,
color corrections extend past the frame of an image. By using the Crop
in the macro, we cut off the Set, making the image ready for transformations.
By setting your alpha value to 0, you can also remove the alpha
channel from the image, i.e., turn a RGBA image into a RGB image.
