Camera.__init__() internally calls UsdGeom.Camera.Define() which
resets aperture to defaults, making it impossible to pre-set values.
The aperture mismatch warnings are cosmetic — IS auto-corrects them
and our values are applied correctly after init.

Camera.__init__() checks aperture consistency against resolution
before we can call set_horizontal_aperture(). Pre-set the aperture
values directly on the USD prim via UsdGeom.Camera API to eliminate
the mismatch warnings.
