Simon Fraser did ask us to slow down on these.

> Source/WebCore/rendering/RenderObject.cpp:1085

It’s inefficient to call enclosingBoundingBox twice here on each quad. This should be rewritten to use a local variable.

> Source/WebCore/rendering/RenderQuote.cpp:70
> +    for (auto quoteCharacter : distinctQuoteCharacters) {

This is *wrong*. It needs to be auto& or this function won’t work.

> Source/WebCore/rendering/style/KeyframeList.cpp:103
> +        for (auto& currKeyframe : m_keyframes) {

Should just be keyframe, not currKeyframe.

> Source/WebCore/rendering/svg/RenderSVGPath.cpp:117
> +            FloatPoint radiusVector(point.x() - location.x(), point.y() -  location.y());

This should be:

    FloatPoint radiusVector = point - location;

> Source/WebCore/rendering/svg/RenderSVGText.cpp:188
>      SVGTextLayoutAttributes* attributes = 0;

nullptr

Then, Do I wait to upload these patches?

I made the local variable to remove the inefficient call.

I Changed it to use the auto&.

This function already use the 'keyframe' for the parameter of function.
So I used the 'currKeyframe' to avoid the confusion.

'point - location' return the FloatSize.
So I changed it to "FloatPoint radiusVector(point - location);"

Done.
