Where is the top/bottom of the screen?

[Mark Wieder]

Richard-

(since you asked...)

The Windows API itself actually uses pixels in most calls, as in for
example GetWindowPlacement(). As I understand it, the idea behind
using twips is that twips are independent of screen resolution and are
guaranteed to be square. In other words, if you define an image on the
screen to be 1440 x 1440 twips you can be sure that it will be
displayed one inch square. The same is not necessarily true if you
define it to be x pixels by x pixels.
