  Technically speaking that description is incomplete. The two vectors do
not only define the size (ie. dimensions) but also the orientation of the
area lights. Using x and z gives you a very different orientation than
using eg. x and y. (Unless you are using 'orient', of course.)
  It should also be noted that using x and z is different from using
x and 2*z, which gives you an area lights twice as long in the z direction
(in this case, in order to get better lighting, you should also double the
density of the grid in that axis, ie. the fourth parameter given to
'area_light').
