Subject: [PATCH] Tests/LibGfx: Add a jbig2 test for transposed text segments

See the PR adding this test for local changes to `jbig2`.
I used the shell script mentioned in #23659, except I added the line
`-txt -Param -Transposed 1` at the very end of the .ini file.

As with all the symbol test cases, after running

    Meta/jbig2_to_pdf.py -o foo.pdf foo.jb2 399 400

the file opens up ok in Chrome and Firefox (but not Safari), so
maybe it's not completely broken.
