This uses more modern calls and custom shaders.
I don't think there is an advantage using this over the simpler example, but it is provided for reference.

## Introduction
This example is the default XCode "OpenGL" example code, modified to support IMGUI and [Synergy](http://synergy-project.org/).
This example is the default XCode "OpenGL" example code, modified to support ImGui and [Synergy](http://synergy-project.org/).
Synergy (remote keyboard/mouse) is not required, but it's pretty hard to use IMGUI without it. Synergy includes a "uSynergy" library that allows embedding a synergy client, this is what is used here. IMGUI supports "Touch Padding", and this is enabled when Synergy is not active.

## C++ on iOS
IMGUI is a c++ library. If you want to include it directly, rename your Obj-C file to have the ".mm" extension.
ImGui is a c++ library. If you want to include it directly, rename your Obj-C file to have the ".mm" extension.
Alternatively, you can wrap your debug code in a C interface, this is what I am demonstrating here with the "debug_hud.h" interface. Either approach works, use whatever you prefer.
In my case, most of my game code is already in C++ so it's not really an issue and I can use IMGUI directly.
