Yes, Size_1 and Size_2.

AXIS_1_VECTOR and AXIS_2_VECTOR set the extent of the area_light.
Size_1 and Size_2 set the number of components, or samples, in the 
area_light.

When using orient, the pairs need to be of the same size. The 
AXIS_n_VECTORs need to have the same length and be perpendicular.
And, you need Size_1 = Size_2.

When using adaptive, always start with adaptive 0 and only increase if 
you really need to.
