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!

ISSUES & TODO-LIST
==================
Issue numbers (#) refer to github issues listed at https://github.com/ocornut/imgui/issues
The list below consist mostly of notes of things to do before they are requested/discussed by users (at that point it usually happens on the github)
The list below consist mostly of ideas noted down before they are requested/discussed by users (at which point it usually moves to the github)
- doc: add a proper documentation+regression testing system (#435)
- window: add a way for very transient windows (non-saved, temporary overlay over hundreds of objects) to "clean" up from the global window list. perhaps a lightweight explicit cleanup pass.
