the code used to keep components in place after changes to the left margin of base glyphs has been rewritten using the algorithm described by @dberlow (thanks!).
the new version produces 100% correct results in all tests made so far, while the previous version had a bug which affected glyphs with multiple versions of the same component.
however, the new version is a lot slower.
TO DO:
look into ways to optimize the component alignment code in functions loadSpacingFromLib and smartSetMargins
