it SET is gravity assuming then its "origin" (i use that loosely) is the
bottom-right. so for example if i have an image in an image viewer. with NW
gravity and if i don't scale the image to fit, it is in the top-left with blank
space as the window resizes to the right and bottom. now if your gravity is SE
- you would want the inverse of the behavior inside the app window reflecting
its "intended" gravity on the screen. well this is one scenario.
