// 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 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"
|
||||
// If you do so 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 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.

||||

// stb_rect_pack.h - v0.11 - public domain - rectangle packing
|
||||
// Sean Barrett 2014
|
||||
//
|
||||
// Useful for e.g. packing rectangular textures into an atlas.
|
||||
// Does not do rotation.
|
||||
//
|
||||
// Not necessarily the awesomest packing method, but better than
|
||||
// the totally naive one in stb_truetype (which is primarily what
|
||||
// this is meant to replace).
|
||||
//
|
||||
// Has only had a few tests run, may have issues.
|
||||
//
|
||||
// More docs to come.
|
||||
//
|
||||
// No memory allocations; uses qsort() and assert() from stdlib.
|
||||
// Can override those by defining STBRP_SORT and STBRP_ASSERT.
|
||||
//
|
||||
// This library currently uses the Skyline Bottom-Left algorithm.
|
||||
//
|
||||
// Please note: better rectangle packers are welcome! Please
|
||||
// implement them to the same API, but with a different init
|
||||
// function.
