Popups: open/close functions
OpenPopup(): set popup state to open. ImGuiPopupFlags are available for opening options.
If not modal: they can be closed by clicking anywhere outside them, or by pressing ESCAPE.
CloseCurrentPopup(): use inside the BeginPopup()/EndPopup() scope to close manually.
CloseCurrentPopup() is called by default by Selectable()/MenuItem() when activated (FIXME: need some options).
Use ImGuiPopupFlags_NoOpenOverExistingPopup to avoid opening a popup if there's already one at the same level. This is equivalent to e.g. testing for !IsAnyPopupOpen() prior to OpenPopup().
Use IsWindowAppearing() after BeginPopup() to tell if a window just opened.
