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>
