Current behaviour:
Attach an object as child to the camera object, while being in front to the camera.
In the game, the object is not visible because his coordinate put the object at a different location

Expect: the object is visible and in front of the camera, like it is in blender.

Workaround: Attach the object only at runtime and not in blender.

Analysis: minigdx rotate the camera to 90 degrees as by default camera's blender is facing down (and not in front).
So any attached object should take this rotation in consideration which is not the case at the moment.
