示例1: CopyBrushToRenderTarget

 /// <summary>
 /// Creates and returns a copy of the brush in the new render target.
 /// Used for changing render targets.
 /// A brush belongs to a render target, so when you want to draw with same brush in another render target
 /// - you need to create a copy of the brush in the new render target.
 /// </summary>
 /// <param name="sourceBrush">The brush.</param>
 /// <param name="newRenderTarget">The new render target.</param>
 /// <returns></returns>
