(Second attempt at landing this) Image formats and graphics APIs use alpha, not transparency, so change our internal formats and data structures to work directly with alpha, so we don't need to modify data before we push it to graphics APIs. Add a couple of new Color constants to make the intention of the vcl code clearer. Notes (*) On macOS, tweaking the logic in CreateWithSalBitmapAndMask to more accurately reflect the requirements of the CGImageCreateWithMask function seems to fix some tests. (*) The vcl code does not properly support gradients with transparency. So the previous code was wrong, and this change is going to result in slightly different wrongness.
