### Q: How can I use the drawing facilities without an ImGui window? (using ImDrawList API)
### Q: How can I use low-level drawing facilities? (using ImDrawList API)
- You can create a dummy window. Call Begin() with the NoBackground | NoDecoration | NoSavedSettings | NoInputs flags.
(The `ImGuiWindowFlags_NoDecoration` flag itself is a shortcut for NoTitleBar | NoResize | NoScrollbar | NoCollapse)
Then you can retrieve the ImDrawList* via GetWindowDrawList() and draw to it in any way you like.
