// ID stack/scopes
// - Read the FAQ for more details about how ID are handled in dear imgui. If you are creating widgets in a loop you most
// likely want to push a unique identifier (e.g. object pointer, loop index) to uniquely differentiate them.
// - The resulting ID are hashes of the entire stack.
// - You can also use the "Label##foobar" syntax within widget label to distinguish them from each others.
// - In this header file we use the "label"/"name" terminology to denote a string that will be displayed and used as an ID,
// whereas "str_id" denote a string that is only used as an ID and not normally displayed.
