This options structure defines optional controls for the creation of the
perspective viewing matrix.

PK_TRANSF_create_view

'have_eye_position'      Whether a perspective 'eye_position' has been
                         provided. If this variable is PK_LOGICAL_true,
                         then the view  matrix will contain the appropriate
                         perspective component and global scale factor.
                         (PK_LOGICAL_false)

'eye_position'           The eye position representing the centre of
                         projection.
