// Because I (Nikolaus Gebhardt) did some changes to Murphy McCauley's loader,
|
|
// I'm writing this down here:
|
|
// - Replaced all dependencies to STL and stdio with irr:: methods/constructs
|
|
// - Disabled logging define
|
|
// - Changed some minor things (Don't remember what exactly.)
|
|
// Thanks a lot to Murphy McCauley for writing this loader.
