I am referring to a different kind of corruption than the one seen in
the gradient bugs I've filed. I'll try to file a separate bug for that
tommorow. In the existing gradient precision bug, the gradient is
misaligned with its stops. In the case I'm referring to, which was
discussed on the list but not filed as a bug, radial and linear
gradients fail to render or become scrambled when any of their
coordinates exceed 32767 pixels, even if only a portion of them is
