//-----------------------------------------------------------------------------
// 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 )

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

//---- Don't implement default handlers for Windows (so as not to link with OpenClipboard() and others Win32 functions)
//#define IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCS
//#define IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCS

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

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

//---- Pack colors to BGRA instead of RGBA (remove need to post process vertex buffer in back ends)
//#define IMGUI_USE_BGRA_PACKED_COLOR

//---- Implement STB libraries in a namespace to avoid conflicts
//#define IMGUI_STB_NAMESPACE     ImGuiStb

//---- Define constructor and implicit cast operators to convert back<>forth from your math types and ImVec2/ImVec4.

#define IM_VEC2_CLASS_EXTRA                                                 \

*/

//---- Use 32-bit vertex indices (instead of default: 16-bit) to allow meshes with more than 64K vertices
//#define ImDrawIdx unsigned int

//---- Tip: You can add extra functions within the ImGui:: namespace, here or in your own headers files.
//---- e.g. create variants of the ImGui::Value() helper for your low-level math types, or your own widgets/helpers.
