- Addresses #6763, #6673 and #2113, but does not perform any feature simplification
- Recommend adding some letter [and word] spacing before applying any delta angle adjustment
- Label is skipped during PAL priority calculation, permitting collisions and overlaps
- Overridden by layer and data defined 'scale/pixel size visibility' and data defined 'show label' options
- Add option to Change Label tool
- Allows user to quickly set visibility thresholds based upon text legibility
- By default initially on for map unit labels to skip rendering at sizes < 3 px
- Adv Labeling option to 'Show upside-down labels': never, when rotation defined, or always
- 'Never' (default) option is same as before, labels with 90 <= angle < 270 are turned so their text is always upright
- 'When rotation defined' option shows upside-down labels if their rotation is layer- or data-defined (dynamic labels are turned upright)
- 'Always' option shows upside-down labels at layer- or data-defined rotations and for dynamic labels
- 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
