Add support to move the camera so that the entire model is visible
Adds QCamera::viewAll(), QCamera::viewEntity() and QCamera::viewSphere()
to move and rotate the camera so that the view center is the center
of the sphere and the sphere fits inside the viewport
Only works in perspective projection.
Introduces a job to compute the bounding sphere of the scene
excluding the camera.
