SVG values animation with keytimes

According to http://www.w3.org/TR/SMIL3/smil-animation.html#adef-keyTimes , the keyTime 1 should be the last time value of an animation. Right now it is the value right after that value. Short example:

<rect width="100" height="100" fill="green">
    <animate attributeName="width" values="100 ; 200 ; 300" calcMode="discrete" keyTimes="0;0.5;1" dur="6" fill="freeze"/>
</rect>

According to http://www.w3.org/TR/SMIL3/smil-animation.html#animationNS-InterpolationIllus the values should change at 2s, 4s and right before 6s. At the moment we take the last value at exactly 6s. According to the spec, it should not affect the animation, because 6s would be excluded. We should check for keyTime 1 and should calculate the last time value right before reaching the end.

While FF, Opera and Batik end the animation with the value 300 for width, we end with 200. 

This affects at least one W3C test: http://dev.w3.org/SVG/profiles/1.1F2/test/svg/animate-elem-31-t.svg
