Message:

Land support for the CSS @font-face rule. This patch allows custom fonts
to be downloaded from the Web and rendered in Web pages. Right now only
TrueType fonts are supported. Proprietary formats like .eot are not
supported.

Reviewed by Eric Seidel

Many tests will be coming in a future landing.

• WebCore.base.exp: Expose some more stuff for WebKit, caused by font restructuring.

• WebCore.xcodeproj/project.pbxproj: Add all the new font face files.

• css/CSSComputedStyleDeclaration.cpp: (WebCore::CSSComputedStyleDeclaration::getPropertyCSSValue): Make sure to ignore the 'src' property of @font-face rules.

• css/CSSFontFace.cpp: Added. (WebCore::CSSFontFace::CSSFontFace): (WebCore::CSSFontFace::~CSSFontFace): (WebCore::CSSFontFace::isLoaded): (WebCore::CSSFontFace::isValid): (WebCore::CSSFontFace::addSource): (WebCore::CSSFontFace::fontLoaded): (WebCore::CSSFontFace::getFontData):
• css/CSSFontFace.h: Added. A CSSFontFace is a composite object. It consists of multiple font-face sources, where each source represents either a remote or local file in a @font-face rule's src list.

• css/CSSFontFaceRule.cpp: (WebCore::CSSFontFaceRule::setDeclaration): (WebCore::CSSFontFaceRule::cssText):
• css/CSSFontFaceRule.h: The implementation of the @font-face rule itself in the CSS sheet back end.

• css/CSSFontFaceSource.cpp: Added. (WebCore::CSSFontFaceSource::CSSFontFaceSource): (WebCore::CSSFontFaceSource::~CSSFontFaceSource): (WebCore::CSSFontFaceSource::pruneTable): (WebCore::CSSFontFaceSource::isLoaded): (WebCore::CSSFontFaceSource::isValid): (WebCore::CSSFontFaceSource::fontLoaded): (WebCore::CSSFontFaceSource::getFontData):
• css/CSSFontFaceSource.h: Added. (WebCore::CSSFontFaceSource::string): (WebCore::CSSFontFaceSource::setFontFace): A font face source represents a single remote or local font. If it represents a remote font than it wraps a CachedFont.

• css/CSSFontFaceSrcValue.h: Added. (WebCore::CSSFontFaceSrcValue::m_isLocal): (WebCore::CSSFontFaceSrcValue::~CSSFontFaceSrcValue): (WebCore::CSSFontFaceSrcValue::resource): (WebCore::CSSFontFaceSrcValue::format): (WebCore::CSSFontFaceSrcValue::isLocal): (WebCore::CSSFontFaceSrcValue::setFormat): Used in parsing. Represents the parsed form of the src value that can then be used to build up a CSSFontFace.

• css/CSSFontSelector.h: Added. The CSS font selector is the object that selects the correct font given a specified font family. It builds up a database of CSSFontFaces that can then be handed back.

• css/CSSGrammar.y:
• css/CSSParser.cpp: (WebCore::CSSParser::parseValue): (WebCore::CSSParser::parseFontFaceSrc): (WebCore::CSSParser::createFontFaceRule):
• css/CSSParser.h: Modify the CSS grammar to now understand @font-face rules.

• css/CSSStyleSelector.h: (WebCore::CSSStyleSelector::fontSelector): The style selector now creates a font selector object and feeds it the appropriate information when @font-face rules are encountered.

• dom/Document.cpp: (WebCore::Document::recalcStyle): Patch the update method now that it takes a font selector argument.
