I'd guess that the program's remembering the position, which would
make lots of sense.

So that's two cases: the program doesn't care, and says (0,0)
                     the program thinks it knows, and says (1487,283) (say)

In the second case I guess it wouldn't be unreasonable for a window
manager to calculate the relative position on the screen and move it
appropriately.  Feels risky but I guess I'm thinking of things like
panels and gkrellm and things, but they're not transient windows
(they're just treated much the same as floating windows).

That leaves a possible class of programs that specify an absolute
position and really mean it.  I can't think of any plausible examples,
but I'd guess it's conceivable.

I've got one application that tries to open a transient in the center
of the screen but doesn't know about Xinerama (so that fails on my
2-screen setup).  So maybe the second case above (where the
application specifies a position) could look to see if the requested
window would be overlapping two screens, and if so could move it?
