When modernizing VTTCue, TextTrackCueGeneric was not sufficiently updated to take advantage of the correct layout implemented by VTTCue. Specifically, TextTrackCueGeneric still queried VTTCueBox::fontSizeFromCaptionUserPrefs(), which was no longer set, and caused the cue width to be incorrectly set to zero. Remove that dead method, and remove most of the implementation of TextTrackCueGenericBoxElement::applyCSSProperties, relying instead upon VTTCueBoxElement's implementation. In order to correctly position TextTrackCueGeneric objects created from AVFoundation, set the resulting cue's positionAlign() to "Center" by way of GenericCueData. This causes VTTCue to position the cue relative to the cue's center point, which is the same way AVFoundation represents the cue's position. * LayoutTests/media/content/test-inband-captions.mp4: Added. * LayoutTests/media/track/track-in-band-layout-expected.txt: Added. * LayoutTests/media/track/track-in-band-layout.html: Added. * Source/WebCore/html/track/InbandGenericTextTrack.cpp: (WebCore::InbandGenericTextTrack::updateCueFromCueData): * Source/WebCore/html/track/TextTrackCueGeneric.cpp: (WebCore::TextTrackCueGenericBoxElement::applyCSSProperties): (WebCore::TextTrackCueGeneric::setBaseFontSizeRelativeToVideoHeight): (WebCore::TextTrackCueGeneric::setFontSizeMultiplier): (WebCore::TextTrackCueGeneric::setFontSize): Deleted. * Source/WebCore/html/track/TextTrackCueGeneric.h: * Source/WebCore/html/track/VTTCue.h: (WebCore::VTTCueBox::setFontSizeFromCaptionUserPrefs): Deleted.
