+ Operator stretching: expose a math data API
+ https://bugs.webkit.org/show_bug.cgi?id=130572
+
+ Reviewed by Chris Fleizach.
+
+ We expose a new SimpleFontData API to give access to the data from the
+ OpenType MATH table using a font cache. The class OpenTypeMathData will
+ be implemented in bug 130324. On Darwin platform, we also implement the
+ missing FontPlatformData::openTypeTable function which will be necessary
+ to load the OpenType MATH table. The changes are intended to be used
+ for MathML operator stretching (bug 130322) so tests are not added yet.
+
+ * CMakeLists.txt: add new OpenTypeMathData files.
+ * WebCore.vcxproj/WebCore.vcxproj: ditto.
+ * WebCore.vcxproj/WebCore.vcxproj.filters: ditto.
+ * WebCore.xcodeproj/project.pbxproj: ditto.
+ * platform/graphics/FontCache.cpp: We add a FontCache::getMathData function to implement a cache for the math data.
+ We make the math and vertical data share the same key for the cache.
+ (WebCore::fontMathDataCacheInstance):
+ (WebCore::FontCache::getMathData):
+ (WebCore::fontVerticalDataCacheInstance):
+ * platform/graphics/FontCache.h: We declare FontCache::getMathData and FontFileKey on all platforms.
+ * platform/graphics/FontPlatformData.cpp:
+ (WebCore::FontPlatformData::openTypeTable): We implement openTypeTable() on Darwin platform.
+ * platform/graphics/FontPlatformData.h: We expose openTypeTable() on Darwin platform.
+ * platform/graphics/SimpleFontData.cpp: We initialize m_mathData from the font cache.
+ (WebCore::SimpleFontData::SimpleFontData):
+ * platform/graphics/SimpleFontData.h: We expose a mathData() function to access the MATH data.
+ * platform/graphics/opentype/OpenTypeMathData.cpp: Added. This is a new class that will be used to parse the data from the OpenType MATH table.
+ (WebCore::OpenTypeMathData::OpenTypeMathData):
+ * platform/graphics/opentype/OpenTypeMathData.h: Added.
+ (WebCore::OpenTypeMathData::create):
+ (WebCore::OpenTypeMathData::hasMathData):
