 It is important to understand the difference between the core Dear ImGui library (files in the root folder)
 and backends which we are describing here (backends/ folder).
 
 - Some issues may only be backend or platform specific.
 - You should be able to write backends for pretty much any platform and any 3D graphics API.

- USING A CUSTOM ENGINE?

-Think twice!
 
-If you are new to Dear ImGui, first try using the existing backends as-is.
+List of Platforms Backends:
-You will save lots of time integrating the library.
-You can LATER decide to rewrite yourself a custom backend if you really need to.
-In most situations, custom backends have less features and more bugs than the standard backends we provide.
-If you want portability, you can use multiple backends and choose between them either at compile time 
-or at runtime. 
-
-Example A: your engine is built over Windows + DirectX11 but you have your own high-level rendering
-system layered over DirectX11.
- - Suggestion: try using imgui_impl_win32.cpp + imgui_impl_dx11.cpp first.
-   Once it works, if you really need it you can replace the imgui_impl_dx11.cpp code with a 
-   custom renderer using your own rendering functions, and keep using the standard Win32 code etc.
-
-Example B: your engine runs on Windows, Mac, Linux and uses DirectX11, Metal, Vulkan respectively.
- - Suggestion: use multiple generic backends!
-   Once it works, if you really need it you can replace parts of backends with your own abstractions.
-
-Example C: your engine runs on platforms we can't provide public backends for (e.g. PS4/PS5, Switch), 
-and you have high-level systems everywhere.
- - Suggestion: try using a non-portable backend first (e.g. win32 + underlying graphics API) to get
-   your desktop builds working first. This will get you running faster and get your acquainted with
-   how Dear ImGui works and is setup. You can then rewrite a custom backend using your own engine API.
-
-Also:
-The multi-viewports feature of the 'docking' branch allows Dear ImGui windows to be seamlessly detached 
-from the main application window. This is achieved using an extra layer to the Platform and Renderer 
-backends, which allows Dear ImGui to communicate platform-specific requests.
-Supporting the multi-viewports feature correctly using 100% of your own abstractions is more difficult 
-than supporting single-viewport.

 The code in imgui.cpp embeds a copy of 'ProggyClean.ttf' (by Tristan Grimmer),
 a 13 pixels high, pixel-perfect font used by default. We embed it in the source code so you can use Dear ImGui without any file system access.
