<rdar://problem/9973489> REGRESSION (r66599): -[DOMNode boundingBox] returns the zero rect for SVG elements
​https://bugs.webkit.org/show_bug.cgi?id=69305

Reviewed by Simon Fraser.

Source/WebCore:

Test: svg/custom/boundingBox.html

Rather than asserting and returning the zero rect, take the transform-aware code path for computing SVG
bounding rects.

  • rendering/svg/RenderSVGForeignObject.cpp:

(WebCore::RenderSVGForeignObject::mapLocalToContainer): Updated for change to SVGRenderSupport::mapLocalToContainer().

  • rendering/svg/RenderSVGInline.cpp:

(WebCore::RenderSVGInline::mapLocalToContainer): Ditto.

  • rendering/svg/RenderSVGModelObject.cpp:

(WebCore::RenderSVGModelObject::mapLocalToContainer): Ditto.
(WebCore::RenderSVGModelObject::absoluteRects): Replaced an incorrect assertion with code to approximate the bounding
box.

  • rendering/svg/RenderSVGText.cpp:

(WebCore::RenderSVGText::mapLocalToContainer): Updated for change to SVGRenderSupport::mapLocalToContainer().

  • rendering/svg/SVGRenderSupport.cpp:

(WebCore::SVGRenderSupport::mapLocalToContainer): Removed the fixed and useTransform boolean parameters.

  • rendering/svg/SVGRenderSupport.h:

LayoutTests:

  • svg/custom/boundingBox-expected.txt: Added.
  • svg/custom/boundingBox.html: Added.
