- Newcomers, read 'PROGRAMMER GUIDE' in imgui.cpp for notes on how to setup ImGui in your codebase.
- Please read the comments and instruction at the top of each file.

Please read the comments and instruction at the top of each file.
- 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. Each imgui_impl_xxxx.cpp comes with its own individual
ChangeLog at the top of the .cpp files, so if you want to update them later it will be easier to
catch up with what changed.
- To LEARN how to setup imgui, you may refer to 'example_glfw_opengl2/' because is the simplest one to read.
However, do NOT USE the OpenGL2 renderer if your code is using any modern GL3+ calls.
Mixing old fixed-pipeline OpenGL2 and modern OpenGL3+ is going to make everything more complicated.
Read comments below for details. If you are not sure, in doubt, use the OpenGL3 renderer.
- Dear ImGui has 0 to 1 frame of lag for most behaviors, at 60 FPS your experience should be pleasant.
However, consider that OS mouse cursors are typically drawn through a specific hardware accelerated path
and will feel smoother than common GPU rendered contents (including Dear ImGui windows).

at 60 FPS will feel slow. It might be beneficial to the user experience to switch to a software rendered
cursor only when an interactive drag is in progress.
Note that some setup or GPU drivers are likely to be causing extra lag depending on their settings.
If you are not sure who to blame if you feeling that dragging something is laggy, try to build an
application drawing a shape directly under the mouse cursor.
If you feel that dragging windows feels laggy and you are not sure who to blame: try to build an

layered over DirectX11.
Example: your engine is built over Windows + DirectX11 but you have your own high-level rendering

Suggestion: step 1: try using imgui_impl_win32.cpp + imgui_impl_dx11.cpp first.
Once this work, _if_ you want you can replace the imgui_impl_dx11.cpp code with a custom renderer
using your own functions, etc.

integration. It is also much more complicated and require more work to integrate correctly.
If you are new to imgui and you are trying to integrate it into your application, first try to ignore
everything related to Viewport and Platform Windows. You'll be able to come back to it later!
Note that if you decide to use unmodified imgui_impl_xxxx.cpp files, you will automatically benefit from
improvements and fixes related to viewports and platform windows without extra work on your side.
