<h3>Log Message</h3>
<pre>Merge <a href="http://trac.webkit.org/projects/webkit/changeset/196052">r196052</a> - ASSERTION FAILED: roundedIntPoint(rendererMappedResult) == roundedIntPoint(result)
https://bugs.webkit.org/show_bug.cgi?id=153576
Patch by Fujii Hironori <Hironori.Fujii@jp.sony.com> on 2016-02-02
Reviewed by Darin Adler.
Source/WebCore:
Tests: fast/block/geometry-map-assertion-with-rounding-negative-half.html
The results of roundedIntPoint of FloatPoint and LayoutPoint may be different
because of the uniqueness of LayoutUnit::round introduced by this bug
<https://bugs.webkit.org/show_bug.cgi?id=107208>.
Should convert a FloatPoint to a LayoutPoint before rounding.
* rendering/RenderGeometryMap.cpp:
(WebCore::RenderGeometryMap::mapToContainer):
LayoutTests:
* fast/block/geometry-map-assertion-with-rounding-negative-half-expected.txt: Added.
* fast/block/geometry-map-assertion-with-rounding-negative-half.html: Added.</pre>
