Reviewed by Simon Fraser.

The writeIndent method and overloaded << operators for writing out vectors and points and rectangles
of various types are not specific to the render tree nor do they depend on any rendering-specific interface.

* page/scrolling/ScrollingStateNode.cpp:
* page/scrolling/ScrollingStateNode.h:
(ScrollingStateNode): Remove the writeIndent declaration, it's functionally the same as the TextStream method.
* platform/graphics/GraphicsLayer.cpp:
* platform/graphics/GraphicsLayer.h:
(GraphicsLayer): Ditto.
* platform/graphics/filters/DistantLightSource.cpp: Remove the RenderTreeAsText.h inclusion or replace it with
the inclusion of the TextStream.h header where required. The writeIndent method is now declared there.
* platform/graphics/filters/FEBlend.cpp: Ditto.
* platform/graphics/filters/FEColorMatrix.cpp: Ditto.
* platform/graphics/filters/FEComponentTransfer.cpp: Ditto.
* platform/graphics/filters/FEComposite.cpp: Ditto.
