I'd like to see how it looks like :)

Well, I want to expand the nodoka configurability for the 0.8.x branch
and in the past I even considered adding these options, but somehow
forgot about it as I started implementing different styles instead (as
you can see in git or at the wiki [1]). But there is a possibility that
I'll implement these, though in a slightly different way. I'd probably
add something like these:

gradient_<gradient_type>_custom = TRUE
gradient_<gradient_type>_stops = {0.0, 0.7, 1.0}
gradient_<gradient_type>_shades = {1.1, 1.105, 1.147}
gradient_<gradient_type>_alpha = {1.0, 1.0, 1.0}

The number of stops might be made configurable and it would be decided
by the number of stops specified in gradient_<gradient_type>_stops.
As how the gradient is implemented in Nodoka now, the <gradient_type>
would be one of these:

out/in/linear/fade/symmetric

though the names would probably need to change to better reflect that
they are configurable...
