[Therion] Progressive coded JPG files??

[Bill Gee]

I have been doing more testing, and Jonny Prouty has made some 
suggestions.  The problem is not resolved, but it seems to me that it 
exists somewhere in the upgrade from Fedora 41 to Fedora 42.

It has been a while (more than two days!), so I do not remember if I 
compiled the current installation before or after doing the Fedora 42 
upgrade.  Both happened about the same time in late April.  Just in 
case, I am going to compile again on a test Fedora 42 machine using 
whatever Therion version is on github today.

Among other things I did verify that the JPG files I am using are NOT 
progressive.  There is a Linux tool called jpeginfo which will tell you 
that, and much more.
