// 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.
