I don't see the problem here. This is what you asked for, and I think people
will ask for.

You can choose the following behaviours for the red region
-- fill with white --- specify color stops "black, white" and
background-repeat:no-repeat
-- fill with transparent (or any other color) --- specify color stops
"black, 100% white, rgba(0,0,0,0)" and background-repeat:no-repeat
-- repeat with black to white --- color stops "black, white" and
background-repeat:repeat (default)
