You are right for windows with a fixed size, for example most dialog
boxes.

But you are wrong for resizeable windows and full screen windows. If
I want to make a nice screen dump of a full size window, I will get a
640x480 pixels graphic on with a 640x480 screen. And I will get a
1280x1024 pixels graphic from a 1280x1024 screen. Etc.

By the way, I have discovered a special problem when using 1280x1024
screendumps: distortion due to W/H ratio. Look here:

640/480 =   1.3333
800/600 =   1.3333
1024/768 =  1.3333
1280/1024 = 1.25
1600/1200 = 1.3333

Wonder who invented 1280x1024? It should have been 1280x960 if it was
to have the same W/H ratio as the rest of them.
