kanzi运行时节点状态展示

背景：有时候kanzi运行后节点不显示，可能是visible/opacity等属性设置不正确，排查困难。做一个实时节点树，方便查看节点信息。

1. 引入imgui

在vs工程里导入glad,glfw,imgui代码
vs属性-链接库，增加glfw3.lib

2. 实现框架

在onProjectLoaded里创建子线程

CreateThread(NULL, 0, multiTask, 0, 0, NULL);

子线程负责创建glfw窗口，刷新，销毁窗口

DWORD WINAPI multiTask(LPVOID p) {
   
    FCreateWindow();
    while (!glfwWindowShouldClose(m_Window)) {
   
        Update();
    }
    Destory();
    return 0;
};

2.1 创建窗口

void FCreateWindow() {
   
    glfwInit();

    const char* glsl_version = "#version 130";
    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 0);
    m_Window = glfwCreateWindow(m_WindowWidth, m_WindowHeight, "Xml", nullptr, nullptr);

    glfwMakeContextCurrent(m_Window);
    glfwSwapInterval(1); // Enable vsync
    int status = gladLoadGLLoader((GLADloadproc)glfwGetProcAddress);

    printf("status-%d\n", status);
    printf("Vendor-%s\n", glGetString(GL_VENDOR));
    printf("Renderer-%s\n", glGetString(GL_RENDERER));
    printf("Version-%s\n", glGetString(GL_VERSION));

    IMGUI_CHECKVERSION();
    ImGui::CreateContext();
    ImGuiIO &io = ImGui::GetIO();
    (void)io;
    io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard; // Enable Keyboard Controls
    // io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad;      // Enable Gamepad Controls
    io.ConfigFlags |= ImGuiConfigFlags_DockingEnable;	// Enable Docking
    io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable; // Enable Multi-Viewport / Platform Windows
    // io.ConfigFlags |= ImGuiConfigFlags_ViewportsNoTaskBarIcons;
    // io.ConfigFlags |= ImGuiConfigFlags_ViewportsNoMerge;

    float fontSize = 18.0f; // *2.0f;
    io.Fonts->AddFontFromFileTTF(("./font/Alimama_DongFangDaKai_Regular.ttf"), fontSize, NULL, io.Fonts->GetGlyphRangesChineseSimplifiedCommon());
    io.FontDefault = io.Fonts->AddFontFromFileTTF(("./font/Alimama_DongFangDaKai_Regular.ttf"), fontSize, NULL, io.Fonts->GetGlyphRangesChineseSimplifiedCommon());

    // Setup Dear ImGui style
    ImGui::StyleColorsDark();
    //ImGui::StyleColorsClassic();

    // When viewports are enabled we tweak WindowRounding/WindowBg so platform windows can look identical to regular ones.
    ImGuiStyle &style = ImGui::GetStyle();
    if (io.ConfigFlags & ImGuiConfigFlags_ViewportsEnable)
    {
   
        style.WindowRounding =
