        Disambiguate "background color" and "contents as solid color" on GraphicsLayer
        https://bugs.webkit.org/show_bug.cgi?id=104842

        Reviewed by NOBODY (OOPS!).

        GraphicsLayer failed to be clear about the distinction between
        the layer background color, and setting the layer contents
        to a color. This caused some recently added tests to fail,
        and required some special-casing for the TileCache in
        GraphicsLayerCA.
        
        Separate these two concepts on GraphicsLayer. setBackgroundColor()
        now sets the background color on the entire layer, which will only
        be used in special cases like the TileCache.
        
        The existing setContentsToBackgroundColor() is renamed to
        setContentsToSolidColor(), and is an explicit request to create
        a contents layer for the purpose of displaying a simple color.
        
        In both cases, 'clear' methods are not necessary; calling
        the setter with an invalid color clears the color.

        Covered by existing tests.

        * WebCore.exp.in: Remove GraphicsLayer::clearBackgroundColor().
        * platform/graphics/GraphicsLayer.cpp:
        (WebCore::GraphicsLayer::GraphicsLayer):
        (WebCore::GraphicsLayer::setBackgroundColor):
        (WebCore::GraphicsLayer::dumpProperties):
        * platform/graphics/GraphicsLayer.h:
        (GraphicsLayer): Remove m_backgroundColorSet; we just check whether
        the color is a valid color now.
        (WebCore::GraphicsLayer::setContentsToSolidColor):
        * platform/graphics/ca/GraphicsLayerCA.cpp:
        (WebCore::GraphicsLayerCA::GraphicsLayerCA):

        (GraphicsLayerCA):
        * rendering/RenderLayerBacking.cpp:
        (WebCore::RenderLayerBacking::updateGraphicsLayerGeometry): We have
        to call updateBackgroundColor(), because the 'is simple compositing layer'
        state may change in this code path.
        (WebCore::RenderLayerBacking::updateBackgroundColor): Don't initialize
        the Color to transparent (it will be invalid initially), and always
        call setContentsToSolidColor() which will either set or remove the color.

		29	Reviewed by NOBODY (OOPS!).
		30
		31	GraphicsLayer failed to be clear about the distinction between
		32	the layer background color, and setting the layer contents
		33	to a color. This caused some recently added tests to fail,
		34	and required some special-casing for the TileCache in
		35	GraphicsLayerCA.
		36
		37	Separate these two concepts on GraphicsLayer. setBackgroundColor()
		38	now sets the background color on the entire layer, which will only
		39	be used in special cases like the TileCache.
		40
		41	The existing setContentsToBackgroundColor() is renamed to
		42	setContentsToSolidColor(), and is an explicit request to create
		43	a contents layer for the purpose of displaying a simple color.
		44
		45	In both cases, 'clear' methods are not necessary; calling
		46	the setter with an invalid color clears the color.
		47
		48	Covered by existing tests.
		49
		50	* WebCore.exp.in: Remove GraphicsLayer::clearBackgroundColor().

73	(WebCore::RenderLayerBacking::updateBackgroundColor): Don't initialize
