Module engine

Contains all the logic for running the animations, execute the scheduled changes to the models, and prepare the render tree The scene is drawn in 4 stages:

• The layout step calculates the dimensions and position of a node and generates a transformation Matrix
• The draw step generates a displaylist
• The render step uses the displaylist to generate a texture of the node
• The compose step generates the final image using the textures

The Engine is the main engine responsible for managing layers and rendering.

Usage:

use layers::prelude::*;

let engine = Engine::create(500.0, 500.0);
let layer = engine.new_layer();
engine.add_layer(&layer);
