Forgot to mention that this fixes two more tests of the W3C test suite:

Almost r=me, still some comments to be resolved, setting r- for the meanwhile.

When a property value is 'inherit' or 'currentColor' during the animation, get the computed style of the property since the values could be animated themselves.

> Source/WebCore/ChangeLog:28

s/with the use of .../by using the CSS property map in SVGStyledElement/.

> Source/WebCore/ChangeLog:30

s/Take..../ -> s/target/targetElement/ for consistency.

> Source/WebCore/ChangeLog:33

s/Check if/.../ -> Checks if the CSS property is animable.

For consistency: avoid the return value, and use a "String& attributeValue" as parameter?

What does that mean?

> Source/WebCore/svg/SVGAnimateElement.cpp:163
> +        // Get current values on property value 'currentColor' as well as 'inherit'

Replace 'currentColor' / 'inherit' by their computed property values.

> Source/WebCore/svg/SVGAnimateElement.cpp:192
> +        // Get current values on property value 'currentColor' and 'inherit'

Same comment as I suggested above. And use periods at the end of sentences.

> Source/WebCore/svg/SVGAnimateElement.h:54
> +    // If we have 'currentColor' or 'inherit' as animation value, we need to grep the value during the animation

s/grep/grab/

Why BasicValueChange? Doesn't make a lot of sense to me.
enum AnimatedPropertyValueType {
RegularPropertyValue,
CurrentColorValue,
InheritValue
}; ?

> Source/WebCore/svg/SVGAnimateElement.h:59
> +        constantBasicValue,
> +        currentColorBasicValue,
> +        inheritBasicValue

Capitalize those enum values.
