Re: Imager-0.38pre9 Released.

    Opps, that message from Arnar contained "This really is the last version
    (we hope) before a CPAN release." I mis-interpreted that to mean Imager
    hadn't been released to CPAN yet at all. That changes everything...

    I like the named parameter interface better and I understand the need for
    backward compatibility. I think it might be a good idea to support both,
    perhaps by checking if the first param is an href then assume named params
    and ignore any remaining list params (there shouldn't be any.)

    We could name the params something like color_red, color_green,
    color_blue...
    or better yet, use a lref to pass all three since they should always go
    together:
    $c = Imager::Color->new(rgb=>[100, 0, 255], alpha=>128);

    > Future additions to the interface are likely to use named parameters.
    Great :-)
