The problem was that rule-based renderer allowed cloned rules to have the same unique rule key.
That in turn created the confusion with checkboxes in legend. Now rules always have new rule key
when cloned. The only exception is when the whole renderer is cloned - in such case we preserve
their rule keys, so that other components (legend / visibility presets) can still keep using
the original rule keys.
Projects where this problem appears need to be fixed - the easiest way is to select all rules,
copy&paste them and remove the previous rules.
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).

Il software è stato realizzato da Gis3W s.a.s.
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
