        Cairo graphics fixes and cleanups

        * platform/graphics/ImageBuffer.h:
        * platform/graphics/cairo/ImageBufferCairo.cpp:
        (WebCore::ImageBuffer::surface): Provide surface() accessor.
        * platform/graphics/cairo/AffineTransformCairo.cpp:
        (WebCore::AffineTransform::rotate): Convert from degrees to radians to
        fix rotation.
        * platform/graphics/cairo/GraphicsContextCairo.cpp:
        (WebCore::GraphicsContext::drawRect): Add save/restore.
        (WebCore::GraphicsContext::rotate): Rename parameter to "radians" to
        avoid further confusion.
        * platform/graphics/cairo/PathCairo.cpp:
        (WebCore::Path::boundingRect): The cairo_fill_extents() parameters do
        not describe a point/size but rather the two control points of the
        rectangular region.
        (WebCore::Path::contains): Remove needless casts.
