* WARNING! Zeropadding of VMRs in AtmFieldsCalc and
AtmFieldsCalcExpand1D has to be enabled explicitly now!

* src/m_atmosphere.cc, src/methods.cc (AtmFieldsCalc,
AtmFieldsCalcExpand1D):

Add flag vmr_zeropadding that is off by default to avoid accidental
padding without the user noticing.

Move description of interp_order from the general method description
into GIN_DESC.

* controlfiles/artscomponents/ppath/TestRefractPlanets.arts:

Enable vmr_zeropadding in AtmFieldsCalc for Venus and Jupiter.
