Cranpose Render Common

cranpose-render-common defines scene, renderer and hit-test contracts for Cranpose backends. Backend authors implement Renderer and RenderScene. App developers select a renderer through cranpose.

Create a graph from a root layer and inspect its node count:

use cranpose_render_common::graph::{LayerNode, RenderGraph};

let graph = RenderGraph::new(LayerNode::default());
assert_eq!(graph.node_count(), 1);

The Renderer contract accepts a LayoutTree or a MemoryApplier root and a logical-pixel viewport. AppShell installs renderer services before the first composition pass. Default features include embedded-default-font, which supplies a fallback font. See the Renderer API, the renderer architecture guide, the renderer source and the crate source.
