//-----------------------------------------------------------------------------
// DEAR IMGUI COMPILE-TIME OPTIONS
// 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 file to verify
// that the data structures your files are using are matching the ones imgui.cpp
// is using.

// call overhead and because we don't guarantee backward nor forward ABI
// compatibility.
// - Windows DLL users: heaps and globals are not shared across DLL boundaries!

// #define IMGUI_USE_STB_SPRINTF

//---- Use FreeType to build and rasterize the font atlas (instead of
// stb_truetype which is embedded by default in Dear ImGui)
// Requires FreeType headers to be available in the include path. Requires
// program to be compiled with 'misc/freetype/imgui_freetype.cpp' (in this
// repository) + the FreeType library (not provided). On Windows you may use
// vcpkg with 'vcpkg install freetype --triplet=x64-windows' + 'vcpkg integrate

//---- Use FreeType + plutosvg or lunasvg to render OpenType SVG fonts (SVGinOT)
// Only works in combination with IMGUI_ENABLE_FREETYPE.
// - plutosvg is currently easier to install, as e.g. it is part of vcpkg. It
// will support more fonts and may load them faster. See misc/freetype/README
// for instructions.
// - Both require headers to be available in the include path + program to be
// linked with the library code (not provided).

// licensed under CeCILL-C Free Software License Agreement)

// stb_truetype backend ALONG with the FreeType backend.
// #define IMGUI_ENABLE_STB_TRUETYPE

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

//---- ...Or use Dear ImGui's own very basic math operators.
// #define IMGUI_DEFINE_MATH_OPERATORS

//---- Use 32-bit vertex indices (default is 16-bit) is one way to allow large
// meshes with more than 64K vertices.
// Your renderer backend will need to support it (most example renderer backends
// support both 16/32-bit indices). Another way to allow large meshes while
// keeping 16-bit indices is to handle ImDrawCmd::VtxOffset in your renderer.
// Read about ImGuiBackendFlags_RendererHasVtxOffset for details.
// #define ImDrawIdx unsigned int

//---- Override ImDrawCallback signature (will need to modify renderer backends
// accordingly) struct ImDrawList; struct ImDrawCmd; typedef void
// (*MyImDrawCallback)(const ImDrawList* draw_list, const ImDrawCmd* cmd, void*
// my_renderer_user_data); #define ImDrawCallback MyImDrawCallback

//---- Debug Tools: Macro to break in Debugger (we provide a default
// implementation of this in the codebase)
// (use 'Metrics->Tools->Item Picker' to pick widgets with the mouse and break
// into them for easy debugging.)
// #define IM_DEBUG_BREAK  IM_ASSERT(0)
// #define IM_DEBUG_BREAK  __debugbreak()

//---- Debug Tools: Enable highlight ID conflicts _before_ hovering items. When
// io.ConfigDebugHighlightIdConflicts is set.
// (THIS WILL SLOW DOWN DEAR IMGUI. Only use occasionally and disable after use)
// #define IMGUI_DEBUG_HIGHLIGHT_ALL_ID_CONFLICTS

//---- Debug Tools: Enable slower asserts
// #define IMGUI_DEBUG_PARANOID

//---- Tip: You can add extra functions within the ImGui:: namespace from
// anywhere (e.g. your own sources/header files)
/*
namespace ImGui
{
    void MyFunction(const char* name, MyMatrix44* mtx);
}
