<pre>Bug 155792 - Basic implementation of mpadded
https://bugs.webkit.org/show_bug.cgi?id=155792
Patch by Frederic Wang <fwang@igalia.com> on 2016-07-07
Reviewed by Brent Fulgham.
Source/WebCore:
We implement a basic support for the mpadded element.
We support most of the attribute values except pseudo-units or negative values.
Tests: mathml/presentation/mpadded-1-2.html
mathml/presentation/mpadded-1.html
mathml/presentation/mpadded-2.html
mathml/presentation/mpadded-3.html
mathml/presentation/mpadded-unsupported-values.html
mathml/presentation/mpadded-dynamic.html
* CMakeLists.txt: Add RenderMathMLPadded to the build system.
* WebCore.xcodeproj/project.pbxproj: Ditto.
* mathml/MathMLInlineContainerElement.cpp:
(WebCore::MathMLInlineContainerElement::createElementRenderer): Create the renderer
for mpadded.
* mathml/mathattrs.in: Add voffset attribute.
* mathml/mathtags.in: Make mpadded use MathMLInlineContainerElement.
* rendering/RenderObject.h:
(WebCore::RenderObject::isRenderMathMLPadded): Define isRenderMathMLPadded.
* rendering/mathml/RenderMathMLPadded.cpp: Added.
We do a simple implementation by overriding the behavior of RenderMathMLRow and forcing
relayout after attribute or style change.
(WebCore::RenderMathMLPadded::RenderMathMLPadded):
(WebCore::RenderMathMLPadded::computePreferredLogicalWidths):
(WebCore::RenderMathMLPadded::layoutBlock):
(WebCore::RenderMathMLPadded::updateFromElement):
(WebCore::RenderMathMLPadded::styleDidChange):
(WebCore::RenderMathMLPadded::firstLineBaseline):
* rendering/mathml/RenderMathMLPadded.h: Added.
LayoutTests:
We import mpadded tests from Mozilla test suite.
We also add some tests for dynamic changes of mpadded attributes and to verify
that the mpadded element behaves as if it had an inferred <mrow>.
Finally, we check that fallback properly for negative and pseudo-unit values that
we do not support yet.
* mathml/presentation/inferred-mrow-baseline.html: Check baseline for mpadded.
* mathml/presentation/inferred-mrow-baseline-expected.txt: Ditto.
* mathml/presentation/inferred-mrow-stretchy.html: Check stretching of operators for mpadded.
* mathml/presentation/inferred-mrow-stretchy-expected.txt: Ditto.
* mathml/presentation/mpadded-dynamic.html: Added. Verify dynamic change of mpadded attributes.
* mathml/presentation/mpadded-dynamic-expected.html: Added. Ditto.
* mathml/presentation/mpadded-unsupported-values.html: Added. Check negative and pseudo-unit values.
* mathml/presentation/mpadded-unsupported-values-expected.html: Added.
* mathml/presentation/mpadded-1-2-expected.html: Added.
* mathml/presentation/mpadded-1-2.html: Added.
* mathml/presentation/mpadded-1-expected.html: Added.
* mathml/presentation/mpadded-1.html: Added.

</span><ins>+ Bug 155792 - Basic implementation of mpadded
+ https://bugs.webkit.org/show_bug.cgi?id=155792
+
+ Reviewed by Brent Fulgham.
+
+ We implement a basic support for the mpadded element.
+ We support most of the attribute values except pseudo-units or negative values.
+
+ Tests: mathml/presentation/mpadded-1-2.html
+ mathml/presentation/mpadded-1.html
+ mathml/presentation/mpadded-2.html
+ mathml/presentation/mpadded-3.html
+ mathml/presentation/mpadded-unsupported-values.html
+ mathml/presentation/mpadded-dynamic.html
+
+ * CMakeLists.txt: Add RenderMathMLPadded to the build system.
+ * WebCore.xcodeproj/project.pbxproj: Ditto.
+ * mathml/MathMLInlineContainerElement.cpp:
+ (WebCore::MathMLInlineContainerElement::createElementRenderer): Create the renderer
+ for mpadded.
+ * mathml/mathattrs.in: Add voffset attribute.
+ * mathml/mathtags.in: Make mpadded use MathMLInlineContainerElement.
+ * rendering/RenderObject.h:
+ (WebCore::RenderObject::isRenderMathMLPadded): Define isRenderMathMLPadded.
+ * rendering/mathml/RenderMathMLPadded.cpp: Added.
+ We do a simple implementation by overriding the behavior of RenderMathMLRow and forcing
+ relayout after attribute or style change.
+ (WebCore::RenderMathMLPadded::RenderMathMLPadded):
+ (WebCore::RenderMathMLPadded::computePreferredLogicalWidths):
+ (WebCore::RenderMathMLPadded::layoutBlock):
+ (WebCore::RenderMathMLPadded::updateFromElement):
+ (WebCore::RenderMathMLPadded::styleDidChange):
+ (WebCore::RenderMathMLPadded::firstLineBaseline):
+ * rendering/mathml/RenderMathMLPadded.h: Added.
