    Some find its effect unsatisfactory because it makes both foreground
    and background colors translucent.  Adrian says the alpha-component
    support in the NS port is superior and actually the latter can make
    background translucent while keeping foreground opaque.

Is there a difficulty in implementing backhground-only transparency on
the other platforms?
