If negative margins are set for a label, the label contents will
begin outside the bounds of the label. This is desirable for
aligning label items with other items while allowing for optical
margin alignment for the label type.
Previously only a single margin setting would apply to both
horizontal and vertical margins. This change allows users to specify
different horizontal and vertical margins.
- update methods of existing classes
- add comment to methods missing in the sip bindings
- split up collective sip files into single files and use
same directory structure in python/ as in src/
- add a lot of missing classes (some might not make sense because of
missing python methods in those classes)
- remove some non-existing methods from the header files
- add scripts/sipdiff
- replace some usages of std::vector and std::set with QVector/QSet
