Example

#include "UltraEngine.h"

using namespace UltraEngine;

    //Get the displays
    auto displays = GetDisplays();

    //Create a window
    auto window = CreateWindow("Ultra Engine", 0, 0, 1280, 720, displays[0], WINDOW_CENTER | WINDOW_TITLEBAR);

    //Create a world

    //Create a framebuffer
    auto framebuffer = CreateFramebuffer(window);

    //Create a camera

    light->SetRotation(45, 35, 0);
    light->SetRange(-10, 10);
