The order of the elements is irrelevant and duplicate elements are unwanted. It
is therefore a perfect candidate for a set instead of a list. This prevents
filtering for duplicates manually be replacing some filer codes with (more
performant) builtin methods of QSet.
Groups nearby points into a single rendered marker symbol.
QgsPointDisplacementRenderer has been split into a new
pure virtual QgsPointDistanceRenderer base class which handles the
detection of clusters and grouping of points. The new cluster
renderer reuses this base class to avoid code duplication.
Additionally, some improvements have been made to the
displacement renderer, specifically:
- points are now assigned to the group which is "nearest" them,
rather then just assigning them first group within the search
distance. In some cases this was assigning features to a more
distant cluster, resulting in less predictable cluster patterns
- individual points are now correctly shown in their own
selection state
Lots of code cleanup + documentation too.

And rename to QgsUnitTypes::RenderUnits. This enum is used in
much more contexts than just symbols, so QgsUnitTypes is a
better fit for it.
All methods which previously accepted QgsSymbolV2::OutputUnit
parameters or QgsSymbolV2::OutputUnitList parameters now take
QgsUnitTypes::RenderUnit or QgsUnitTypes::RenderUnitList
parameters respectively.

Move embedded renderer handling to QgsFeatureRendererV2 and
add support for embedded renders to legend context menu
Fix#14967
* make sip coverage test aware that there are less classes where QSci sip
headers are not available
* exclude properties from members
* fix QgsFeatureIds typedef (fixes missing signal
QgsVectorLayer.featuresDeleted and others)
* add missing notes for PyNames
* include some missing new methods in bindings
I'm not sure what sip voodoo is preventing the bindings from
calling methods in the base class, so for QGIS <3.0 I've aliased
all the new signatures and will rename them back for 3.0
the single, graduated and categorised symbol renderers have been
refactored to avoid use of raw pointers (auto_ptr are used instead, they
are deprecated in c++11 but the change for unique_ptr is an easy one and
they clearly state the design intend: exclusive ownership)
2 general use function to quote and unquote strings for/from xml have
been added to qgis.h
- 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
