- API BREAKING CHANGES (read me when you update!)
- FREQUENTLY ASKED QUESTIONS (FAQ), TIPS
- Can I have multiple widgets with the same label? (Yes)
- How do I update to a newer version of ImGui?
- Why is my text output blurry?
- How can I load a different font than the default?
- How can I load multiple fonts?

e.g. when displaying a single object that may change over time (1-1 relationship), using a static string as ID will preserve your node open/closed state when the targeted object change.
e.g. when displaying a list of objects, using indices or pointers as ID will preserve the node open/closed state differently. experiment and see what makes more sense!
Q: How do I update to a newer version of ImGui?
A: Overwrite the following files:
imgui.cpp
imgui.h
stb_rect_pack.h
stb_textedit.h
stb_truetype.h
Check the "API BREAKING CHANGES" sections for a list of occasional API breaking changes.
Q: Why is my text output blurry?
A: In your Render function, try translating your projection matrix by (0.5f,0.5f) or (0.375f,0.375f)
