Description of problem:
Discovered an if-then that should have been removed before version 20190731
https://github.com/fontforge/libspiro/blob/master/ChangeLog

This is mainly for the benefit of graphics, like GIMP, IPE (FontForge not affected). major distros like Fedora and Debian have already bumped-up.

Version-Release number of selected component (if applicable):
currently at 20200505. Asking to please update to 20221101


How reproducible:
Correct scaling factor should be absolute values of X or Y
Incorrect if-then decision chooses the larger dimension for scaling, therefore if ABS(-xdistance) is larger than +ydistance, ydistance is chosen for scaling because it is positive, vs -ve xdistance which should have been used.

The differences in results could on average not be visibly noticed for roundish/squarish objects, due to applied scaling and rounding but might be noticed with elongated objects, like say maybe an elongated type bar if no rounding applied.
In summary - it's a bugfix.
