Indeed. Good suggestions.

Yes... but, most modern monitors have exactly a 16:9 aspect ratio.
The ubiquitous 1920x1080 is 16:9.

Most, but not all.

Two 1920x1200 displays here. (And a third one tucked away in a box.)

In general, displays targeted at end-users are pretty much all 16:9; 
those targeted at people who do actual work with them come at 16:10 
surprisingly(?) frequently.

In their office range of displays, Eizo for instance currently offers 
more displays @ 1920x1200 than @ 1920x1080 (10 vs. 8).

In their photo/video editing range of displays, they don't even offer 
1920x1080; in that ballpark, 1920x1200 is the only thing they offer. (At 
higher resolution, they're tending towards 16:9 though, too, or even 17:9.)

Oh, and one thing I forgot to mention entirely:

If you're using POV-Ray v3.8 or higher, and start you scene with

#version 3.8;

(as you should), then your sphere should automagically be round 
regardless of image size, even without messing with `right` and/or `up`.

At least that's what I had written in `changes.txt` some glorious day, 
so it must be true. Totally forgot that I implemented that.
