        [chromium] simplify complex text code, fixing a handful of layout tests
        https://bugs.webkit.org/show_bug.cgi?id=52661

        Change ComplexTextControllerLinux to lay out RTL text to the left from
        the starting point.  (Previously it always went to the right.)  This allows
        us to map pixel offsets more directly into offsets within the text runs,
        simplifying a few of the text-fiddling functions (they no longer need to
        track the current position, as ComplexTextController now does it).

        * platform/graphics/chromium/ComplexTextControllerLinux.cpp:
        (WebCore::ComplexTextController::ComplexTextController):
        (WebCore::ComplexTextController::reset):
        (WebCore::ComplexTextController::setGlyphXPositions):
        * platform/graphics/chromium/ComplexTextControllerLinux.h:
        (WebCore::ComplexTextController::offsetX):
        * platform/graphics/chromium/FontLinux.cpp:
        (WebCore::Font::drawComplexText):
        (WebCore::Font::floatWidthForComplexText):
        (WebCore::glyphIndexForXPositionInScriptRun):
        (WebCore::Font::offsetForPositionForComplexText):
        (WebCore::Font::selectionRectForComplexText):
