        Canvas: 2d.fillStyle.parse.system.html fails
        https://bugs.webkit.org/show_bug.cgi?id=39168

        Based on previous work by Julien Chaffraix <jchaffraix@codeaurora.org>
        and Jan Erik Hanssen <jhanssen@sencha.com>

        * css/CSSParser.cpp:
        (WebCore::CSSParser::parseColor): Changed the function to better match our
        early return policy. Also we now return false when we don't parse the color.
        This is needed for createFromString to fallback to using parseSystemColor.

        (WebCore::CSSParser::parseSystemColor): Made use of the RenderTheme to get
        the system colors.

        * css/CSSParser.h: Added the new parseSystemColor method.

        * html/canvas/CanvasRenderingContext2D.cpp:
        (WebCore::CanvasRenderingContext2D::setStrokeColor): Pass the document to createFromString.
        (WebCore::CanvasRenderingContext2D::setFillColor): Ditto.

        * html/canvas/CanvasStyle.cpp:
        (WebCore::parseColor):
        (WebCore::parseColorOrCurrentColor):
        (WebCore::CanvasStyle::createFromString): Try to parse the color using CSSParser::parseColor
        and fall back to parseSystemColor if it did not work.

        * html/canvas/CanvasStyle.h: Added the new Document* parameter to createFromString.
