<pre>Use parameters from the OpenType MATH table for <munderover>
https://bugs.webkit.org/show_bug.cgi?id=155756
Patch by Frederic Wang <fwang@igalia.com> on 2016-07-11
Reviewed by Brent Fulgham.
Source/WebCore:
We follow the description from the MathML in HTML5 implementation
to improve the layout of <munderover> using some constants from the MATH table.
Tests: imported/mathml-in-html5/mathml/presentation-markup/scripts/underover-parameters-1.html
imported/mathml-in-html5/mathml/presentation-markup/scripts/underover-parameters-2.html
imported/mathml-in-html5/mathml/presentation-markup/scripts/underover-parameters-3.html
imported/mathml-in-html5/mathml/presentation-markup/scripts/underover-parameters-4.html
mathml/presentation/attributes-accent-accentunder-dynamic.html
* mathml/mathattrs.in: Add accentunder attribute.
* rendering/mathml/MathMLOperatorDictionary.h: Remove FIXME comment.
* rendering/mathml/RenderMathMLUnderOver.cpp:
(WebCore::RenderMathMLUnderOver::hasAccent): Helper function to determine whether
the over/under script should be treated as an accent.
(WebCore::RenderMathMLUnderOver::getVerticalParameters): Helper function to read
some vertical parameters from the MATH table.
(WebCore::RenderMathMLUnderOver::layoutBlock): Take into account the new vertical
parameters for the layout of <munderover>.
* rendering/mathml/RenderMathMLUnderOver.h: Define new helper functions.
LayoutTests:
Import some tests from the MathML in HTML5 test suite to verify
the layout of the <munderover> element. We also write a test to
verify dynamic change of accent/accentunder attributes and adjust
other tests.

font to make the result more reliable.</pre>

</span><ins>+ Use parameters from the OpenType MATH table for <munderover>
+ https://bugs.webkit.org/show_bug.cgi?id=155756
+
+ Reviewed by Brent Fulgham.
+
+ We follow the description from the MathML in HTML5 implementation
+ to improve the layout of <munderover> using some constants from the MATH table.
+
+ Tests: imported/mathml-in-html5/mathml/presentation-markup/scripts/underover-parameters-1.html
+ imported/mathml-in-html5/mathml/presentation-markup/scripts/underover-parameters-2.html
+ imported/mathml-in-html5/mathml/presentation-markup/scripts/underover-parameters-3.html
+ imported/mathml-in-html5/mathml/presentation-markup/scripts/underover-parameters-4.html
+ mathml/presentation/attributes-accent-accentunder-dynamic.html
+
+ * mathml/mathattrs.in: Add accentunder attribute.
+ * rendering/mathml/MathMLOperatorDictionary.h: Remove FIXME comment.
+ * rendering/mathml/RenderMathMLUnderOver.cpp:
+ (WebCore::RenderMathMLUnderOver::hasAccent): Helper function to determine whether
+ the over/under script should be treated as an accent.
+ (WebCore::RenderMathMLUnderOver::getVerticalParameters): Helper function to read
+ some vertical parameters from the MATH table.
+ (WebCore::RenderMathMLUnderOver::layoutBlock): Take into account the new vertical
+ parameters for the layout of <munderover>.
+ * rendering/mathml/RenderMathMLUnderOver.h: Define new helper functions.
