// [DEAR IMGUI]
|

// This is a slightly modified version of stb_rect_pack.h 1.00.
|
||||
// Those changes would need to be pushed into nothings/stb:
|
||||
// - Added STBRP__CDECL
|
||||
// This is a slightly modified version of stb_rect_pack.h 1.01.

|

// Sean Barrett 2014
|
||||
//
|
||||
// Useful for e.g. packing rectangular textures into an atlas.
|
||||
// Does not do rotation.

//
|

// #define STB_RECT_PACK_IMPLEMENTATION
|

//
|
||||
// in the file that you want to have the implementation.
|
||||
//
|
||||
// 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).
