<pre>Use Fraction* parameters from the OpenType MATH table
https://bugs.webkit.org/show_bug.cgi?id=155639
Source/WebCore:
Patch by Frederic Wang <fwang@igalia.com> on 2016-03-20
Reviewed by Brent Fulgham.
We improve the RenderMathMLFraction so minimal vertical shifts and gaps
from the MATH table (or arbitrary fallback) are used for fractions.
We also change the interpretation of "thick" and "thin" linethickness values
to match Gecko's behavior and the one suggested in the MathML in HTML5 implementation note.
Test: imported/mathml-in-html5/mathml/presentation-markup/fractions/frac-parameters-1.html
* rendering/mathml/MathMLStyle.cpp:
(WebCore::MathMLStyle::updateStyleIfNeeded): set NeedsLayout after displaystyle change
so that dynamic MathML tests still work.
* rendering/mathml/RenderMathMLFraction.cpp:
(WebCore::RenderMathMLFraction::RenderMathMLFraction): Init LayoutUnit members to zero.
(WebCore::RenderMathMLFraction::updateFromElement):
Set new members for fraction gaps and shifts using Fraction* constants or some fallback
values. Change the interpretation of "thick" and "thin".
(WebCore::RenderMathMLFraction::layoutBlock): Use new constants affecting vertical
positions of numerator and denominator.
(WebCore::RenderMathMLFraction::paint): Use m_ascent to set the vertical position
of the fraction bar.
(WebCore::RenderMathMLFraction::firstLineBaseline): We just return m_ascent.
* rendering/mathml/RenderMathMLFraction.h: Make updateFromElement public so that
it can be used in MathMLStyle. Add LayoutUnit members for the ascent of the fraction
and for minimal shifts/gaps values.

Reviewed by Brent Fulgham.
We import a test from the MathML in HTML5 test suite to verify Fraction* parameters.
We also do some small test adjustments.
* TestExpectations: We disable fractions-positions.html for now until it is replaced with a more reliable test.

+
+ Use Fraction* parameters from the OpenType MATH table
+ https://bugs.webkit.org/show_bug.cgi?id=155639
+
+ Reviewed by Brent Fulgham.
+
+ We improve the RenderMathMLFraction so minimal vertical shifts and gaps
+ from the MATH table (or arbitrary fallback) are used for fractions.
+ We also change the interpretation of "thick" and "thin" linethickness values
+ to match Gecko's behavior and the one suggested in the MathML in HTML5 implementation note.
+
+ Test: imported/mathml-in-html5/mathml/presentation-markup/fractions/frac-parameters-1.html
+
+ * rendering/mathml/MathMLStyle.cpp:
+ (WebCore::MathMLStyle::updateStyleIfNeeded): set NeedsLayout after displaystyle change
+ so that dynamic MathML tests still work.
+ * rendering/mathml/RenderMathMLFraction.cpp:
+ (WebCore::RenderMathMLFraction::RenderMathMLFraction): Init LayoutUnit members to zero.
+ (WebCore::RenderMathMLFraction::updateFromElement):
+ Set new members for fraction gaps and shifts using Fraction* constants or some fallback
+ values. Change the interpretation of "thick" and "thin".
+ (WebCore::RenderMathMLFraction::layoutBlock): Use new constants affecting vertical
+ positions of numerator and denominator.
+ (WebCore::RenderMathMLFraction::paint): Use m_ascent to set the vertical position
+ of the fraction bar.
+ (WebCore::RenderMathMLFraction::firstLineBaseline): We just return m_ascent.
+ * rendering/mathml/RenderMathMLFraction.h: Make updateFromElement public so that
+ it can be used in MathMLStyle. Add LayoutUnit members for the ascent of the fraction
+ and for minimal shifts/gaps values.
