//   -

// Gameplan
// v Entrypoint
// v Logging
// v Events
// v Window
// v Settings loader (json)
// v Input polling
// v OpenGL context
// - GPUDriver (?)
// v Renderer

//   - Schene (camera, lights, environment)
// - Texture loading
// - Model loading
// - Entity Component System
// - Serialization
// - Level format
// - Tools (Tiled?)
// - Scripting (Lua)

// - Global object access can be done in 3 ways:
// - Singleton, static, extern

// @Todo
// - Settings should contain all file paths (ex: shaders)
// - RefPtr<>
// - Rename Application::get() to Application::the() for singleton
