Look_at is just an alternate representation of several of the other
parameters.  You cannot adjust both representations and expect POV-Ray to
guess which one or combination to use.  That is why POV-Ray 3.5 does apply
all parameters in a well-specified order.

Using matrix is the way to go for your problem unless you don't want to use
look_at.
