I'd like to see area lights consisting of a 1x1 array fully supported, 
so that I can use the jittering of one light source to accomplish the 
area lighting.  With a high AA level, this actually works quite well, 
and if I'm already sampling at a high AA level for some other reason, 
having one jittered point light is just as good, and much faster, than 
an area light with more lights in it.

There is also a feature for meshes in which if the supplied normals are 
all the same, the triangle is treated as a flat mesh and the normals are 
ignored.  There are some effects that can be achieved by eliminating 
this "optimization," such as making a polygon that doesn't have its 
vertices all in the same plane, but has a uniform normal for lighting 
calculations, so that it looks flat.

Regards,
John
