// Popups: open/close functions
// - OpenPopup(): set popup state to open.
// - 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).

// - IMPORTANT: Notice that BeginPopupContextXXX takes ImGuiPopupFlags just like OpenPopup() and unlike BeginPopup(). For full consistency, we may add ImGuiWindowFlags to the BeginPopupContextXXX functions in the future.
// - We exceptionally default their flags to 1 (== ImGuiPopupFlags_MouseButtonRight) for backward compatibility with older API taking 'int mouse_button = 1' parameter. Passing a mouse button to ImGuiPopupFlags is guaranteed to be legal.

// Popups: test function
// - IsPopupOpen(): return true if the popup is open at the current BeginPopup() level of the popup stack.
// - IsPopupOpen() with ImGuiPopupFlags_AnyPopupId: return true if any popup is open at the current BeginPopup() level of the popup stack.
// Flags for OpenPopup*(), BeginPopupContext*(), IsPopupOpen() functions.
// - To be backward compatible with older API which took an 'int mouse_button = 1' argument, we need to treat
// small flags values as a mouse button index, so we encode the mouse button in the first few bits of the flags.
// It is therefore guaranteed to be legal to pass a mouse button index in ImGuiPopupFlags.
// - For the same reason, we exceptionally default the ImGuiPopupFlags argument of BeginPopupContextXXX functions to 1 instead of 0.
