When enabled, this normalize the strength by the light area, to keep
the total output the same regardless of shape or size. This is the
existing behavior.
This is supported in Cycles, EEVEE, Hydra, USD, COLLADA.
For add-ons, an API function to compute the area is added for conversion,
in case there is no native support for normalization.
area = light.area(matrix_world=ob.matrix_world)

Similar to other renderers, this adds a temperature property to set the
light color using blackbody emission. This can be more convenient than
using nodes, and can improve interop with other software.
This is supported in Cycles, EEVEE, Hydra, USD, COLLADA and FBX.

Similar to other renderers, this adds an exposure property to multiply
the light power by 2^exposure. This can be more convenient to control
a wide range of values.
This is supported in Cycles, EEVEE, Hydra, USD, COLLADA and FBX.
