Thanks for taking the time to look into this, Drahken.

Right, I forgot to mention that
High quality zoom is always turned off for both
Reduce and
Enlarge in my XnView installation.
As for Paint Shop Pro, there is a slider in the
Display and Caching preferences:
Code: Select all
Zoom / Rescaling Quality
[ · · · · · · · · · · · · · · ●]
Faster Better

Zoom / Rescaling Quality slider to set whether the Zoom tool quality is faster or better.
Faster will zoom images faster, but will display less fine detail. Better will zoom images more slowly, but display more fine detail.
I had it set to its maximum, but to my surprise I couldn't spot any difference between “fastest” and “best” (even post-restart).
After decompressing/converting
test.jpeg to BMP format with each of the programs listed in my initial post, I opened
Fireworks.bmp,
Picture_Publisher.bmp etc. in XnView's Compare panel. The screenshot(s) were then made at a zoom level of 600%.

Xnview with high quality zoom enabled displays it as very soft and almost smeared. I am unable to recreate the result you got in photoshop & psp9.
<-- EDIT -- //
Paint Shop Pro prior to version 8 came with
jpeglib.dll.
Versions 8+9+X+XI rely on
gdiplus.dll (Microsoft Windows
GDI+ Library) and
jpegacc.dll for dealing with JPEGs.
- ThumbsPlus 7 & Paint Shop Photo Album 5: jpegacc.dll (AccuSoft ImageGear Imaging Toolkit)
- Animation Shop 3 & Paint Shop Pro 7: jpeglib.dll (IJG JPEG library)
- CorelDRAW Graphics Suite 11: iejpg110.flt (Corel JPEG Import/Export Filter) & ibjpg2.flt (ImageStream JPG Graphic Import Filter)
