If you end up creating a custom backend for your engine, you may want to do the same.
An application usually combines 1 Platform backend + 1 Renderer backend + main Dear ImGui sources.

VERSION 1.82 WIP (In Progresss)
-----------------------------------------------------------------------
Breaking Changes:
- Style: renamed rarely used style.CircleSegmentMaxError (old default = 1.60f)
to style.CircleTessellationMaxError (new default = 0.30f) as its meaning changed. (#3808) [@thedmd]
Other Changes:
- ImDrawList: AddCircle, AddCircleFilled(): Tweaked default segment count calculation to honor MaxError
with more accuracy. Made default segment count always even for better looking result. (#3808) [@thedmd]
- ImDrawList: AddCircle, AddCircleFilled(): New default for style.
- Backends: OpenGL, Vulkan, DX9, DX10, DX11, DX12, Metal, WebGPU, Allegro: Rework blending equation to
preserve alpha in output buffer (using SrcBlendAlpha = ONE, DstBlendAlpha = ONE_MINUS_SRC_ALPHA consistently
accross all backends), facilitating compositing of the output buffer with another buffer.
(#2693, #2764, #2766, #2873, #3447, #3813, #3816) [@ocornut, @thedmd, @ShawnM427, @Ubpa, @aiekick]
- Examples: Reworked setup of clear color to be compatible with transparent values.
- CI: Use a dedicated "scheduled" workflow to trigger scheduled builds. Forks may disable this workflow if
scheduled builds builds are not required. [@rokups]

you may use GetMainViewport()->Pos to offset hard-coded positions, e.g. SetNextWindowPos(GetMainViewport()->Pos)
