+/*******************************************************************************************
+*
+*   raylib [models] example - loading gltf with animations
+*
+*   LIMITATIONS:
+*     - Only supports 1 armature per file, and skips loading it if there are multiple armatures
+*     - Only supports linear interpolation (default method in Blender when checked
+*       "Always Sample Animations" when exporting a GLTF file)
+*     - Only supports translation/rotation/scale animation channel.path,
+*       weights not considered (i.e. morph targets)
+*
+*   Example originally created with raylib 3.7, last time updated with raylib 4.2
+*
+*   Example licensed under an unmodified zlib/libpng license, which is an OSI-certified,
+*   BSD-like license that allows static linking with closed source software
