def self.new(bounds : Graphene::Rect)
#
Creates a GskRenderNode that will render a cairo surface
into the area given by @bounds.
You can draw to the cairo surface using Gsk::CairoNode#draw_context.

def draw_context : Cairo::Context
#
Creates a Cairo context for drawing using the surface associated to the render node.
If no surface exists yet, a surface will be created optimized for rendering to @renderer.
