>+        * accessibility/mac/WebAccessibilityObjectWrapperBase.mm:

>+        (-[WebAccessibilityObjectWrapperBase convertPathToScreenSpace:]): Use CFAutorelease

>+        would be to use RetainPtr for the return type instead.

>+        (AXAttributeStringSetColor): Use __bridge for bridging typecast, rearranging
>+        code so that the typecasts are on function arguments, not local variables,
>+        which makes lifetimes clearer.
