Reviewed by Chris Fleizach.

Source/WebCore:

When computing the accessible bounding box of an
SVG root, be sure to call a method that uses transforms,
otherwise an assertion fails.

Newly unskipped tests: accessibility/svg-bounds.html and
accessibility/svg-remote-element.html

* accessibility/AccessibilityRenderObject.cpp:
(WebCore::AccessibilityRenderObject::boundingBoxRect):

Source/WebKit/chromium:

Exposes the clickPoint accessibility method in WebAccessibilityObject.

* public/WebAccessibilityObject.h:
(WebAccessibilityObject):
* src/WebAccessibilityObject.cpp:
(WebKit::WebAccessibilityObject::clickPoint):
(WebKit):

Tools:

Implement clickPointX, clickPointY, and elementAtPoint for Chromium, so that
several more tests can pass.

* DumpRenderTree/chromium/TestRunner/src/AccessibilityUIElementChromium.cpp:
(WebTestRunner::AccessibilityUIElement::AccessibilityUIElement):
(WebTestRunner::AccessibilityUIElement::clickPointXGetterCallback):
(WebTestRunner):
(WebTestRunner::AccessibilityUIElement::clickPointYGetterCallback):
(WebTestRunner::AccessibilityUIElement::elementAtPointCallback):
* DumpRenderTree/chromium/TestRunner/src/AccessibilityUIElementChromium.h:
(AccessibilityUIElement):

LayoutTests:

Enable four more tests now that clickPointX, clickPointY,
and elementAtPoint are implemented for Chromium.

Minor fixes to two tests to make them more robust
across platfoms and when run in parallel.

* accessibility/svg-bounds.html: Updated
* accessibility/svg-bounds-expected.txt: Added (made cross-platform
* accessibility/svg-remote-element.html: Updated
* accessibility/svg-remote-element-expected.txt: Added (made cross-platform)
