cascade option for dev.new?

I frequently run scripts that generate multiple graphs.  Unless you specify a specific window location, dev.new superimposes all new graphics windows exactly on top of each other.  It would be nice to have a "cascade=TRUE" option in dev.new to prevent windows from being hidden.  A hasty approximation to this is the following function:

# utility function to prevent overlapping plot windows
cascade <- function( k=dev.cur(),x0=300,y0=50,dx=30,dy=30){ 
  dev.new( xpos=x0+k*dx, ypos=y0+k*dy); 
  invisible() }

x <- seq(-10,10,.1); y <- sin(x)
plot(x,y,type='l',main='first plot')
cascade()
plot(x,y,type='l',main='second plot')

dev.new just passes arguments on to the device selected.  *If* such 
an argument were appropriate, it would need to added to the screen 
devices, only some of which even have *pos arguments.

On the relatively few occasions I want multiple screeen devices open, 
I want to control their size and location in ways different from the 
defaults so would call X11() or quartz() directly.

If you find your suggestion has widespread support (and I've seen none 
so far), you are welcome to implement it on all relevant devices (and 
we don't even know your OS -- see the posting guide) and submit 
patches for consideration.
