I strongly disagree with disregarding the angle here. If I specify an
angle, I should get that angle, not some random transformation of it
depending on the size of the box. If I want the gradient to size with
the box, then I should specify it in start and end points because those
are defined to be relative to the box.

Changing the angle when I give an angle is considerably more "magic"
than actually drawing the angle I specified.
