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
Rationale:
- there was a lot of large objects passed by value, so potentially
there's a speed bump from this
- even for implicitly shared classes like QString/QList there's still
a (small) cost for copying the objects when there's no reason to
- it's the right thing to do!
The rotation is no longer saved in the Qgs*SymbolRendererV2 but in the
QgsMarkerSymbolV2 in a QgsDataDefined. This commit fixes the legacy API and
redirects calls to the new API.
The graduated symbol renderer now allows to use varying size instead of
varying color.
The classification remains the same an tabbed size/color in the gui
allows the use to choose one type or the other.
There is new "filter" button in layers panel that toggles this functionality
and in composer legend widget.
Related feature is that layer tree now shows symbols in map units with correct size
(even when filtering is not enabled) so as the map view changes the legend node icons
are updated too (if they use map units).
GetLegendGraphics in WMS server
-------------------------------
This is an extension of standard GetLegendGraphics request according to MapServer RFC 101.
See the document for more details: http://mapserver.org/development/rfc/ms-rfc-101.html
In summary, clients need to add BBOX and CRS/SRS parameters to get appropriate legend based on the given map view.
Parameters WIDTH and HEIGHT are also taken into account as they specify map view image size for correct calculation
of size of legend symbols (if they are based on map units).

Fixes several crashes and problems with backwards compatibility.
Before expressions were allowed, field names were loaded and saved
unquoted, e.g. x.y - with introduction of expressions it was
necessary to use properly quoted "x.y" name so that expression
is correctly parsed. With these changes both options are possible
and when possible, the unquoted field name is used for compatibility
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
