    I was going through the bug https://bugs.webkit.org/show_bug.cgi?id=48290, which passes is FF but fails in Safari/Winlauncher( r87771)

As per http://www.w3.org/TR/2011/WD-2dcontext-20110525/#compositing, "highlight" is NOT a valid composite operation. but it is being mentioned in platform/graphics/GraphicsTypes.cpp in compositeOperatorNames[] & that's why this issue is present.

When I removed "highlight" from here & also removed "CompositeHighLight  from enum CompositeOperator in GraphicsType.h this issue is resolved (I also had to comment out all other code using CompositeHighLight    & CSSValueHighlight.

However, the following comment was mentioned in GraphicsType.h ("    // Note: These constants exactly match the NSCompositeOperator constants of
    // AppKit on Mac OS X Tiger. If these ever change, we'll need to change the
    // Mac OS X Tiger platform code to map one to the other. "). So I am little unclear what is the purpose of this CompositeHighLight.
