Well, it's says that Box>Box used only for Model>Sprite collusions, or am I wrong?
BTW, your code doesn't show, that c_rotate uses box shape. Rotate entity with it, and set GLIDE flag on, you'll see. And there is no way, for c_trace to have ellipsoid shape, but box for c_move and c_rotate, as
You mixing many things up. Box-Box means Model->Model OR Model-Sprite without POLYGON activated. And if you activate GLIDE the model doesn't even rotate, it also moves.
And of course my example shows that c_rotate uses box shape. It rotates a box and gives results if a collision detection happend or not. If it would use an ellipsoid, it wouldn't recognize a collision on the edge corners of the box, but it does.
Your quote of the manual that c_moves makes use of c_trace is right for sure. It says an ellipsoid is used for POLYGONAL entities. For BOX entities it uses still a box shape:
