As a Photoshop example, say your left and right source images, 
called "S-L" and "S-R", are each 1100 pixels wide by 1200 pixels 
tall. Create two new blank image files (named "C-L" and "C-R") 
1000 pixels wide and 1100 pixels tall ("a bit smaller"). Now you 
have four images to work with on the display. Click on "S-L" to 
give it "focus", press ctrl-a to select the entire image, then press 
ctrl-c to copy the entire image to the clipboard, click on "C-L", 
then press ctrl-v to paste the entire image into the smaller 
frame.

The entire image is there, though you can only view the portion 
that the smaller frame allows (just like a film chip and its 
mount window). After pasting thus, you move the image within 
the smaller frame, by dragging with the mouse for coarse 
adjustments, or by using the arrow keys. You might have to 
select the Move tool (just press "v" on the keyboard) and click 
in the image to make this work.

To set the stereo window actively, you just position the "C-L" 
and "C-R" images to your liking, and move the source images 
around within their frames. When satisfied, you "flatten" and 
export or save them as jpegs and you're done.

Makes little difference. If you have a well-mounted stereo slide, 
perhaps you can get by with just the scanned images of the 
chips as mounted. But the chances are there will be some less 
than "clean" portions of the scan, right at the edges of the 
mount windows. So you'd still have to either crop this away in 
the raw images after scanning, or be extremely careful when 
selecting the area to be scanned. Imo, it's easier to have the 
scan include a wider area and then use the method outlined 
above.

Nobody is going to convince you otherwise. Perhaps an 
imperfect analogy, concerning the importance of the stereo 
window to stereo photography, might be with the food we eat. 
You could say it doesn't really matter how it tastes, so long as it 
provides nutrition. But lots of people enjoy the extra effort 
taken to produce delicious food, as cook, consumer, or both.
