Unfortunately in 2018 it is still tedious to create and maintain portable build files using external
libraries (the kind we're using here to create a window and render 3D triangles) without relying on

- Batch files for Visual Studio 2008+
- A .sln project file for Visual Studio 2010+
- A .sln project file for Visual Studio 2010+
- Xcode project files for the Apple examples
Please let me know if they don't work with your setup!
You can probably just import the imgui_impl_xxx.cpp/.h files into your own codebase or compile those
directly with a command-line compiler.
example_allegro5/
Allegro 5 example.
= main.cpp + imgui_impl_allegro5.cpp
example_apple_metal/
OSX & iOS + Metal.
= main.m + imgui_impl_osx.mm + imgui_impl_metal.mm
It is based on the "cross-platform" game template provided with Xcode as of Xcode 9.
(NB: imgui_impl_osx.mm is currently not as feature complete as other platforms back-ends.
You may prefer to use the GLFW Or SDL back-ends, which will also support Windows and Linux.)

Note that other examples based on SDL or GLFW + OpenGL could easily be modified to work with Emscripten.
We provide this to make the Emscripten differences obvious, and have them not pollute all other examples.
example_glfw_metal/
GLFW (Mac) + Metal example.

**Prefer using OPENGL3 code (with gl3w/glew/glad, you can replace the OpenGL function loader)**
This code is mostly provided as a reference to learn about Dear ImGui integration, because it is shorter.
If your code is using GL3+ context or any semi modern OpenGL calls, using this renderer is likely to
make things more complicated, will require your code to reset many OpenGL attributes to their initial
state, and might confuse your GPU driver. One star, not recommended.

GLFW (Win32, Mac, Linux) + OpenGL3+/ES2/ES3 example (programmable pipeline).

This uses more modern OpenGL calls and custom shaders.
Prefer using that if you are using modern OpenGL in your application (anything with shaders).
(Please be mindful that accessing OpenGL3+ functions requires a function loader, which are a frequent
source for confusion for new users. We use a loader in imgui_impl_opengl3.cpp which may be different
from the one your app normally use. Read imgui_impl_opengl3.h for details and how to change it.)

Null example, compile and link imgui, create context, run headless with no inputs and no graphics output.

This is used to quickly test compilation of core imgui files in as many setups as possible.
Because this application doesn't create a window nor a graphic context, there's no graphics output.

Allegro doesn't support them natively, so we have two solutions: convert the indices manually in imgui_impl_allegro5.cpp, or compile dear imgui with 32-bit indices.
You can either modify imconfig.h that comes with Dear ImGui (easier), or set a C++ preprocessor option IMGUI_USER_CONFIG to find to a filename.
We are providing `imconfig_allegro5.h` that enables 32-bit indices.
Note that the back-end supports _BOTH_ 16-bit and 32-bit indices, but 32-bit indices will be slightly faster as they won't require a manual conversion.

// - Desktop GL: 2.x 3.x 4.x
// - Embedded GL: ES 2.0 (WebGL 1.0), ES 3.0 (WebGL 2.0)
// This needs to be used along with a Platform Binding (e.g. GLFW, SDL, Win32, custom..)
// (Note: We are using GL3W as a helper library to access OpenGL functions since there is no standard header to access modern OpenGL functions easily. Alternatives are GLEW, Glad, etc..)

// [x] Renderer: Desktop GL only: Support for large meshes (64k+ vertices) with 16-bits indices.
// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
