struct Viewport {
    float x = 0.0f;
    float y = 0.0f;
    float width = 0.0f;
    float height = 0.0f;
    float minDepth = 0.0f;
    float maxDepth = 1.0f;

    Viewport() = default;
    Viewport(float x, float y, float w, float h);
    Viewport(float x, float y, float w, float h, float minD, float maxD);
};
