        Added Qt-specific expected result for toDataURL test, since Qt
        does not support saving pixmaps to GIF.

        * platform/qt/fast/canvas/toDataURL-supportedTypes-expected.txt: Added.

        Rubber-stamped by Simon Hausmann.

        Added Qt-specific expected result for Canvas getImageData's test.

        https://bugs.webkit.org/show_bug.cgi?id=22150

        Since Qt is internally using premultiplied ARGB32 for doing
        alpha-blending painting, reading the color back will not
        necessarily give the same exact color.

        * platform/qt/Skipped: Excluded canvas-getImageData.
        * platform/qt/fast/canvas/canvas-getImageData-expected.txt: Added.

        Updated expected results after Qt's GraphicsContext fixes.

        Reviewed by Simon Hausmann.

        Added Qt-specific expected result for color conversion.

        This is to compensate the lack of color profile in Qt to do
        color conversion, hence CMYK 0,0,0,1 always give pure black (#000)
        instead of very dark black.

        * platform/qt/fast/canvas/set-colors-expected.txt: Added.

        [Qt] Reuse FontPlatformData for the same FontDescription.
        This effectively prevents growing heap usage for loading every web page.

        * platform/graphics/qt/FontCacheQt.cpp:
        (WebCore::qHash): Necessary for FontPlatformDataCache.
        (WebCore::FontCache::getCachedFontPlatformData): Reuse the instance if
        it exists, otherwise create a new one and insert it in the cache.

        [Qt] Fix the leak in FontFallbackList::fontDataAt() function.
        When creating a new instance of SimpleFontData, put it in the font list
        so that it can deleted later on.

        [Qt] In the image decoder, remove the raw image data represented as QImage
        once the image is converted to QPixmap and inserted in the pixmap cache.
        This effectively reduces the heap usage when running on graphics system
        other than raster (i.e the case where QImage != QPixmap).

        * platform/graphics/qt/ImageDecoderQt.cpp:
        (WebCore::ImageDecoderQt::imageAtIndex): Nullified the image on purpose.
        * platform/graphics/qt/ImageDecoderQt.h: Made m_imageList mutable.

        [Qt] Refactor alpha channel detection the image decoder.
        Sets the boolean flag as soon as the image is being read.

        * platform/graphics/qt/ImageDecoderQt.cpp:
        (WebCore::ImageDecoderQt::ImageDecoderQt): Initialized m_hasAlphaChannel.
        (WebCore::ImageDecoderQt::setData): Set the flag when appropriate.
        (WebCore::ImageDecoderQt::supportsAlpha): Simplified.
        (WebCore::ImageDecoderQt::reset): Resetted the flag.
        * platform/graphics/qt/ImageDecoderQt.h: Added m_hasAlphaChannel.
