Don't interpolate between keywords

Browse Source 
Transitioning between linear gradients like
linear-gradient(to top, yellow, green) and
linear-gradient(to left, yellow, green) was yielding
nonsensical results, with the gradient line jumping around
wildly. Fix this by falling back to stupid image interpolation
for these cases.
