// Push a new ImGui window to add widgets to.
// - A default window called "Debug" is automatically stacked at the beginning of every frame so you can use widgets without explicitly calling a Begin/End pair.
// - Begin/End can be called multiple times during the frame with the same window name to append content.
// - The window name is used as a unique identifier to preserve window information across frames (and save rudimentary information to the .ini file).
// You can use the "##" or "###" markers to use the same label with different id, or same id with different label. See documentation at the top of this file.
// - Return false when window is collapsed, so you can early out in your code. You always need to call ImGui::End() even if false is returned.
// - Passing 'bool* p_open' displays a Close button on the upper-right corner of the window, the pointed value will be set to false when the button is pressed.
