dear imgui (AKA ImGui), is a bloat-free graphical user interface library for C++. It outputs optimized vertex buffers that you can render anytime in your 3D-pipeline enabled application. It is fast, portable, renderer agnostic and self-contained (no external dependencies).
ImGui is designed to enable fast iteration and empower programmers to create content creation tools and visualization/debug tools (as opposed to UI for the average end-user). It favors simplicity and productivity toward this goal, and thus lacks certain features normally found in more high-level libraries.

ImGui outputs vertex buffers and simple command-lists that you can render in your application. The number of draw calls and state changes is typically very small. Because it doesn't know or touch graphics state directly, you can call ImGui commands anywhere in your code (e.g. in the middle of a running algorithm, or in the middle of your own rendering process). Refer to the sample applications in the examples/ folder for instructions on how to integrate ImGui with your existing codebase.
_A common misunderstanding is that some people think immediate mode gui == immediate mode rendering, which usually implies hammering your driver/GPU with a bunch of inefficient draw calls and state changes, as the gui functions as called by the user. Some lazy IMGUI-style librairies may work this way but 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. The draw call batches are rather optimal and you can render them later, in your app or even remotely._
ImGui allows you create elaborate tools as well as very short-lived ones. On the extreme side of short-liveness: using the Edit&Continue feature of modern compilers you can add a few widgets to tweaks variables while your application is running, and remove the code a minute later! ImGui is not just for tweaking values. You can use it to trace a running algorithm by just emitting text commands. You can use it along with your own reflection data to browse your dataset live. You can use it to expose the internals of a subsystem in your engine, to create a logger, an inspection tool, a profiler, a debugger, etc.

<b>How do you use ImGui on a platform that may not have a mouse or keyboard?</b>
I recommend using [Synergy](http://synergy-project.org) ([sources](https://github.com/synergy/synergy)). In particular, the _src/micro/uSynergy.c_ file contains a small client that you can use on any platform to connect to your host PC. You can seamlessly use your PC input devices from a video game console or a tablet. ImGui allows to increase the hit box of widgets (via the _TouchPadding_ setting) to accommodate a little for the lack of precision of touch inputs, but it is recommended you use a mouse to allow optimising for screen real-estate.

TL;DR;
- Newcomers, read 'PROGRAMMER GUIDE' in imgui.cpp for notes on how to setup ImGui in your codebase.
- Refer to 'opengl_example' to understand how the library is setup, it is the simplest one.
- Refer to 'opengl2_example' to LEARN how the library is setup, it is the simplest one.
The other examples requires more boilerplate and are harder to read.
- If you are using OpenGL in your application, probably use an opengl3_xxx backend.
Mixing old fixed pipeline OpenGL2 and programmable pipeline OpenGL3+ isn't well supported by drivers.
- If you are using of the backend provided here, so you can copy the imgui_impl_xxx.cpp/h files
to your project and use them unmodified.

Also note that some setup or GPU drivers may be causing extra lag (possibly by enforcing triple buffering),
