Bug 166674 – Add some missing longhand properties to CSSComputedStyleDeclaration and fix default values

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Joseph Pecoraro]

Summary:
Add some missing longhand properties to CSSComputedStyleDeclaration and fix default values

Test:
<style>
body { counter-reset: my-counter; }
#x { counter-increment: object; }
#x:before {
    content: "Before (" counter(my-counter) ") ";
    counter-increment: my-counter;
}
#x:after {
	content: " After (" counter(my-counter) ")";
    counter-increment: my-counter;
}
</style>
<div id="x">Test</div>

Steps to Reproduce:
1. Inspect div#x on test page
2. Show computed styles
  => "counter-increment" does not show up, but it is expected

Notes:
- This is because "counter-increment" doesn't show up in the numeric list of all longhand properties in: getComputedStyle(elem)
- Adding it to that list makes it show up in the inspector
- Auditing all our longhand properties there are plenty that could be in this list that are not.

Looks like one SVG test still needs fixing.

How can I see what that one SVG test was? =/

Regressions: Unexpected text-only failures (1)
  svg/css/getComputedStyle-basic.xhtml [ Failure ]

Given this function no longer ever returns null, its return type should be changed from RefPtr to Ref.
