Don't see why you couldn't. You can still specify angles in the syntax I
suggested. Though looking back, I do see that I accidentally missed a
grouping; sorry if that was the source of the confusion. Let me fix that:

<linear-gradient> = linear-gradient(
[
    [
        <angle>
        |
        [ top | bottom | left | right [to [ top | bottom | left | right] ]?
]
    ], <color-stop>[, <color-stop>]+
);

Is this different from the transition that has to occur when transitioning
from 0deg to 45deg on a square box? (Or 0deg to 30deg on a box with a
1:sqrt(3) ratio for the sides?) Not a trivial matter either way, but it is
not adding any calculation that doesn't have to be done in unrelated
circumstances.
