I may have misunderstood things, but isn't the angled linear gradient
still just a linear gradient in 2d? I am trying to visualise the
situation, but it's a bit hard...

If I understand this correctly, one "just" has to compute the angle and
create a linear gradient with this angle.

What am I missing?

Cheers,
Uli
