Since you've got a CameraOp*, access the matrix methods directly on it rather
than going through the Op knob interface.
On AxisOp:: there's matrix methods to directly get the Matrix4 - just make sure
you've validate()'d the Op after setting parameters so the matrix is up to
date. Only the local transform matrix (AxisOp::local()) is directly set by the
Axis_Knob, the concatenated final transform matrix (AxisOp::matrix()) is
constructed in validate.
