// You can seek and display only the lines that are visible using the ImGuiListClipper helper, if your elements are evenly spaced and you have cheap random access to the elements.

// A typical application wanting coarse clipping and filtering may want to pre-compute an array of indices that passed the filtering test, recomputing this array when user changes the filter,
// and appending newly elements as they are inserted. This is left as a task to the user until we can manage to improve this example code!
