  // COMPILE-TIME OPTIONS FOR DEAR IMGUI
  // Runtime options (clipboard callbacks, enabling various features, etc.) can generally be set via the ImGuiIO structure.
  // You can use ImGui::SetAllocatorFunctions() before calling ImGui::CreateContext() to rewire memory allocation functions.
  //-----------------------------------------------------------------------------
  // A) You may edit imconfig.h (and not overwrite it when updating Dear ImGui, or maintain a patch/rebased branch with your modifications to it)
  // B) or '#define IMGUI_USER_CONFIG "my_imgui_config.h"' in your project and then add directives in your own file without touching this template.
  //-----------------------------------------------------------------------------
  // You need to make sure that configuration settings are defined consistently _everywhere_ Dear ImGui is used, which include the imgui*.cpp
  // files but also _any_ of your code that uses Dear ImGui. This is because some compile-time options have an affect on data structures.
  // Defining those options in imconfig.h will ensure every compilation unit gets to see the same data structure layouts.
  // Call IMGUI_CHECKVERSION() from your .cpp files to verify that the data structures your files are using are matching the ones imgui.cpp is using.
  //-----------------------------------------------------------------------------

  //---- Define attributes of all API symbols declarations, e.g. for DLL under Windows
  // Using Dear ImGui via a shared library is not recommended, because of function call overhead and because we don't guarantee backward nor forward ABI compatibility.
  // DLL users: heaps and globals are not shared across DLL boundaries! You will need to call SetCurrentContext() + SetAllocatorFunctions()
  // for each static/DLL boundary you are calling from. Read "Context and Memory Allocators" section of imgui.cpp for more details.
