* If you need to rotate object around itself e.g. center of object or at

*
* Even if object's model transform is identity, rotation may not be around
* center of object if object does not lay out at ORIGIN perfectly.
*
* Using `glm_rotate_at()` with center of bounding shape ( AABB, Sphere ... )
* would be an easy option to rotate around object if object is not at origin.
*
* One another option to rotate around itself at any point is `glm_spin()`
* which is perfect if only rotating around model position is desired e.g. not
* specific point on model for instance center of geometry or center of mass,
* again if geometry is not perfectly centered at origin at identity transform,
* rotation may not be around geometry.

cglm tried to enable print functions in debug mode and disable them in
release/production mode to eliminate printing costs.
if you need to force enable then define CGLM_DEFINE_PRINTS macro not DEBUG one
Print functions are enabled if:
- DEBUG or _DEBUG macro is defined (mostly defined automatically in debugging)
- CGLM_DEFINE_PRINTS macro is defined including release/production
which makes enabled printing always
- glmc_ calls for io are always prints
