_A common misunderstanding is to mistake immediate mode gui for immediate mode rendering, which usually implies hammering your driver/GPU with a bunch of inefficient draw calls and state changes as the gui functions are called. This is NOT what Dear ImGui does. Dear ImGui outputs vertex buffers and a small list of draw calls batches. It never touches your GPU directly.

"I first discovered the IMGUI paradigm at [Q-Games](http://www.q-games.com) where Atman Binstock had dropped his own simple implementation in the codebase, which I spent quite some time improving and thinking about. It turned out that Atman was exposed to the concept directly by working with Casey. When I moved to Media Molecule I rewrote a new library trying to overcome the flaws and limitations of the first one I've worked with. It became this library and since then I have spent an unreasonable amount of time iterating and improving it."

// Usage:
// ImGuiListClipper clipper(1000); // we have 1000 elements, evenly spaced.
// ImGuiListClipper clipper;
// while (clipper.Step())
// clipper.Begin(1000); // We have 1000 elements, evenly spaced.

// while (clipper.Step())
// ImGui::Text("line number %d", i);
// for (int i = clipper.DisplayStart; i < clipper.DisplayEnd; i++)
// - Step 0: the clipper let you process the first element, regardless of it being visible or not, so we can measure the element height (step skipped if we passed a known height as second arg to constructor).
// ImGui::Text("line number %d", i);
// - Step 1: the clipper infer height from first element, calculate the actual range of elements to display, and position the cursor before the first element.
// Generally what happens is:
// - (Step 2: empty step only required if an explicit items_height was passed to constructor or Begin() and user call Step(). Does nothing and switch to Step 3.)
// - Clipper lets you process the first element (DisplayStart = 0, DisplayEnd = 1) regardless of it being visible or not.
// - Step 3: the clipper validate that we have reached the expected Y position (corresponding to element DisplayEnd), advance the cursor to the end of the list and then returns 'false' to end the loop.
// - User code submit one element.
// - Clipper can measure the height of the first element
// - Clipper calculate the actual range of elements to display based on the current clipping rectangle, position the cursor before the first visible element.
// - User code submit visible elements.
