Profile of gearflowers.svg being rendered

Part of this is that it is a 521k file on a slow server. A local copy takes on
order of 3 seconds to render on a dual 2 GHz G5 here. 7.9% of the time is
consumed in CoreGraphic's getNextAxialShadingScanline, which may be somewhat
optimizable. Other gradient-related functions are taking up a significant chunk
of time, athough the only WebCore function is cgGradientCallback.

See attached shark profile.
