I'm not sure this does what you're implying. You could specify the
position using those keywords, but that would only give you additional
ways of specifying the top left corner of a rectangle, or the center of a
circle. It's nice, but it's sugar, not new functionality.

I think a keyword like this could be added to either argument syntax. I'm
in the middle of an email summarizing the two options - hopefully I can
get it posted in the next few minutes before the thread passes it by
completely.
