[3dprinter-general] slic3r-prusa REMOVED from testing

[Gregor Riepl]

Hi everyone,

It took a while, but I think I managed to iron out the issues in 
PrusaSlicer. Testing on non-amd64 proved to be more work than I had 
anticipated.

The build failures on multiple architectures[1] were caused by two 
separate issues:
1. Bug #1057630 [2]: This one only manifested on i386, but it actually 
affected all platforms. Upstream already discovered and fixed the issue, 
as it was causing their Windows builds to fail.
2. Incorrect floating-point comparison with 0.0 in unit tests. I assumed 
catch2::WithinRel would work well with all fp comparisons, but this is 
not the case with numbers close to zero. In this case, catch2::WitinAbs 
should be used instead. @hyperair pointed this out here: [3].

In any case, I pushed appropriate patches and also the changes from the 
2.6.1+dfsg-4.1 NMU to Salsa. I didn't reopen #1054697, as this seemed a 
bit redundant.

Please release 2.6.1+dfsg-5 when you can! Thank you.

Regards,
Greg
