//-----------------------------------------------------------------------------
// USER IMPLEMENTATION
// This file contains compile-time options for ImGui.
// Other options (memory allocation overrides, callbacks, etc.) can be set at runtime via the ImGuiIO structure - ImGui::GetIO().
//-----------------------------------------------------------------------------

#pragma once

//---- Define assertion handler. Defaults to calling assert().
//#define IM_ASSERT(_EXPR)  MyAssert(_EXPR)

//---- Define attributes of all API symbols declarations, e.g. for DLL under Windows.
//#define IMGUI_API __declspec( dllexport )
//#define IMGUI_API __declspec( dllimport )

//---- Don't define obsolete functions names. Consider enabling from time to time or when updating to reduce likelihood of using already obsolete function/names
//#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS

//---- Don't implement default handlers for Windows (so as not to link with certain functions)
//#define IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCTIONS   // Don't use and link with OpenClipboard/GetClipboardData/CloseClipboard etc.
//#define IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS         // Don't use and link with ImmGetContext/ImmSetCompositionWindow.

//---- Don't implement demo windows functionality (ShowDemoWindow()/ShowStyleEditor()/ShowUserGuide() methods will be empty)
//---- It is very strongly recommended to NOT disable the demo windows. Please read the comment at the top of imgui_demo.cpp.
//#define IMGUI_DISABLE_DEMO_WINDOWS

//---- Don't implement ImFormatString(), ImFormatStringV() so you can reimplement them yourself.
//#define IMGUI_DISABLE_FORMAT_STRING_FUNCTIONS

//---- Include imgui_user.h at the end of imgui.h as a convenience
//#define IMGUI_INCLUDE_IMGUI_USER_H

//---- Pack colors to BGRA8 instead of RGBA8 (if you needed to convert from one to another anyway)
//#define IMGUI_USE_BGRA_PACKED_COLOR

//---- Implement STB libraries in a namespace to avoid linkage conflicts (defaults to global namespace)
//#define IMGUI_STB_NAMESPACE     ImGuiStb

//---- Define constructor and implicit cast operators to convert back<>forth from your math types and ImVec2/ImVec4.
// This will be inlined as part of ImVec2 and ImVec4 class declarations.

#define IM_VEC2_CLASS_EXTRA                                                 \

*/

//---- Use 32-bit vertex indices (instead of default 16-bit) to allow meshes with more than 64K vertices. Render function needs to support it.
//#define ImDrawIdx unsigned int

//---- Tip: You can add extra functions within the ImGui:: namespace, here or in your own headers files.
