Yes, and I believe Twitcher had mistakenly thought the second two numbers
were for the dimension rather than a grid of points (sublights).

So to clarify that, if so, x and z are the size or area. Use 0.7*x,0.7*z,2,2
to get the result intended. Like Warp said, 1 by 1 is no good.

I checked, and sure enough, the error isn't informative unless you already
know what's going on. Probably should tell the user about a minimal grid
size of points needed for the area light when less than 1 is used just as it
does when it is greater than 1 and less than 2. Oddly enough it's giving a
good error message when negatives are used that are -1 or less but it isn't
doing so for all decimals between -1 and 1.
