Check the "API BREAKING CHANGES" sections for a list of occasional API breaking changes. If you have a problem with a function, search for its name
in the code, there will likely be a comment about it. Please report any issue to the GitHub page!
Q: What is ImTextureID and how do I display an image?
A: ImTextureID is a void* used to pass renderer-agnostic texture references around until it hits your render function.
ImGui knows nothing about what those bits represent, it just passes them around. It is up to you to decide what you want the void* to carry!
It could be an identifier to your OpenGL texture (cast GLuint to void*), a pointer to your custom engine material (cast MyMaterial* to void*), etc.
At the end of the chain, your renderer takes this void* to cast it back into whatever it needs to select a current texture to render.
Refer to examples applications, where each renderer (in a imgui_impl_xxxx.cpp file) is treating ImTextureID as a different thing.
(c++ tip: OpenGL uses integers to identify textures. You can safely store an integer into a void*, just cast it to void*, don't take it's address!)
To display a custom image/texture within an ImGui window, you may use ImGui::Image(), ImGui::ImageButton(), ImDrawList::AddImage() functions.
ImGui will generate the geometry and draw calls using the ImTextureID that you passed and which your renderer can use.
It is your responsibility to get textures uploaded to your GPU.

Q. I integrated ImGui in my engine and some elements are disappearing when I move windows around..
Most likely you are mishandling the clipping rectangles in your render function. Rectangles provided by ImGui are defined as (x1,y1,x2,y2) and NOT as (x1,y1,width,height).
