Actually that's always been referred to as a grow box. See Inside Macintosh
I if you know anyone with something that old, the more recent black Inside
Mac series, or in the current Window Manager Reference PDF you'll find:

"kWindowCanGrow
If this bit (bit 0) is set, the window has a grow box (may not be
visible)."

From CarbonEvents.h in 10.3:

* kEventClassWindow / kEventWindowDrawGrowBox
*
* Summary:
* When the DrawGrowIcon API is called, this event is sent to the
* window to tell it to draw the grow box.

If you do a partial word search of the headers for "GrowBox" you'll get
multiple hits in five or six different headers.

Starting in Jaguar you can use kHIViewWindowGrowBoxID to get the grow box
HIView and install a {kEventClassControl, kEventControlDraw} handler on it,
or you can try my previous suggestion of installing a {kEventClassWindow,
kEventWindowDrawGrowBox} handler on the window. And finally, I think there's
an alternative grow box you can using in Panther for windows where you want
minimal interference with the background of the window. You may want to
consider that, as it would be more consistent with other applications.
