/**
* gsk_renderer_create_fallback:
* @renderer: a #GskRenderer
* @viewport: the viewport for the fallback renderer
* @cr: a Cairo context
*
* Creates a fallback #GskRenderer using the same display and window of
* the given @renderer, and instructs it to render to a given Cairo
* context.
*
* Typically, you'll use this function to implement fallback rendering
* of #GskRenderNodes on an intermediate Cairo context, instead of using
* the drawing context associated to a #GdkWindow's rendering buffer.
*
* Returns: (transfer full): a newly created fallback #GskRenderer instance
*
* Since: 3.90
