Implement the mmultiscripts tag https://bugs.webkit.org/show_bug.cgi?id=99618 Patch by Frédéric Wang <fred.wang@free.fr> on 2013-09-15 Reviewed by Chris Fleizach. Source/WebCore: Tests: mathml/invalid-scripts-crash.html mathml/presentation/multiscripts-equivalence.html mathml/presentation/multiscripts-noscripts.html mathml/presentation/multiscripts-positions.html mathml/presentation/scripts-base-alignment.html mathml/presentation/scripts-horizontal-alignment.html mathml/presentation/scripts-vertical-alignment.html mathml/scripts-addChild.html mathml/scripts-removeChild.html This relies on the existing msub/msup/msubsup code to implement the mmultiscripts tag. This also improves dynamic addition/removal of children for these MathML elements and adds a specific style for invalid children, so that they render like an merror tag. Finally, this fixes a bad memory access in the Accessibility render object of msubsup. * CMakeLists.txt: * GNUmakefile.list.am: * Target.pri: * WebCore.vcxproj/WebCore.vcxproj: * WebCore.vcxproj/WebCore.vcxproj.filters: * WebCore.xcodeproj/project.pbxproj: * accessibility/AccessibilityRenderObject.cpp: (WebCore::AccessibilityRenderObject::isMathSubscriptSuperscript): (WebCore::AccessibilityRenderObject::mathSuperscriptObject): * css/mathml.css: (mo, mrow, mfenced, mfrac, msub, msup, msubsup, mmultiscripts, mprescripts, none, munder, mover, munderover, msqrt, mroot): (mover > :last-child, munderover > :last-child): (msub > * + *, msup > * + *, msubsup > * + *, mmultiscripts > * + *, munder > * + *, mover > * + *, munderover > * + *): (merror, msub > * + * + *, msup > * + * + *, msubsup > * + * + * + *, msub > mprescripts, msup > mprescripts, msubsup > mprescripts, msub > none, msup > none, msubsup > none, mmultiscripts > mprescripts ~ mprescripts, mmultiscripts > mprescripts ~ mprescripts ~ *): * mathml/MathMLInlineContainerElement.cpp: (WebCore::MathMLInlineContainerElement::createRenderer): * mathml/mathtags.in: * rendering/mathml/RenderMathMLBlock.h: (WebCore::RenderMathMLBlock::isRenderMathMLScripts): (WebCore::RenderMathMLBlock::isRenderMathMLScriptsWrapper): * rendering/mathml/RenderMathMLScripts.cpp: Added.
