// USER IMPLEMENTATION // COMPILE-TIME OPTIONS FOR DEAR IMGUI
// This file contains compile-time options for ImGui. // Runtime options (clipboard callbacks, enabling various features, etc.) can generally be set via the ImGuiIO structure.
// Other options (memory allocation overrides, callbacks, etc.) can be set at runtime via the ImGuiIO structure - ImGui::GetIO(). // 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 imgui, or maintain a patch/branch with your modifications to imconfig.h)
// B) or add configuration directives in your own file and compile with #define IMGUI_USER_CONFIG "myfilename.h"
// C) Many compile-time options have an effect on data structures. They need defined consistently _everywhere_ imgui.h is included,
// not only for the imgui*.cpp compilation units. Defining those options in imconfig.h will ensure they correctly get used everywhere.

// (minor and older changes stripped away, please see git history for details)
// 2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors and ImGuiBackendFlags_HasSetMousePos flags + honor ImGuiConfigFlags_NoMouseCursorChange flag.
// 2018-03-06: OpenGL: Added const char* glsl_version parameter to ImGui_ImplGlfwGL3_Init() so user can override the GLSL version e.g. "#version 150".
// 2018-02-23: OpenGL: Create the VAO in the render function so the setup can more easily be used with multiple shared GL context.
// 2018-02-20: Inputs: Added support for mouse cursors (ImGui::GetMouseCursor() value and WM_SETCURSOR message handling).
// 2018-02-20: Inputs: Renamed GLFW callbacks exposed in .h to not include GL3 in their name.
// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplGlfwGL3_RenderDrawData() in the .h file so you can call it yourself.
// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
// 2018-02-06: Inputs: Added mapping for ImGuiKey_Space.
// 2018-01-25: Inputs: Added gamepad support if ImGuiConfigFlags_NavEnableGamepad is set.
// 2018-01-25: Inputs: Honoring the io.WantSetMousePos flag by repositioning the mouse (ImGuiConfigFlags_NavEnableSetMousePos is set).
// 2018-01-20: Inputs: Added Horizontal Mouse Wheel support.
// 2018-01-18: Inputs: Added mapping for ImGuiKey_Insert.
// 2018-01-07: OpenGL: Changed GLSL shader version from 330 to 150. (Also changed GL context from 3.3 to 3.2 in example's main.cpp)
// 2017-09-01: OpenGL: Save and restore current bound sampler. Save and restore current polygon mode.
// 2017-08-25: Inputs: MousePos set to -FLT_MAX,-FLT_MAX when mouse is unavailable/missing (instead of -1,-1).
// 2017-05-01: OpenGL: Fixed save and restore of current blend function state.
// 2016-10-15: Misc: Added a void* user_data parameter to Clipboard function handlers.
// 2016-09-05: OpenGL: Fixed save and restore of current scissor rectangle.
// 2016-04-30: OpenGL: Fixed save and restore of current GL_ACTIVE_TEXTURE.
