The line symbol layer as been refactored to avoid code duplication and
expose the offset and offset units in the base class. Note that
the added functions in the base class where already defined in all
child classes.
The functionality can be used in other renderers too, the only requirement
is that legend nodes need to specify their parent rule key via data().
Note that ayer tree model must have ShowLegendAsTree flag enabled, otherwise
the model will keep showing lists instead of trees.
Allows for live, dynamic heatmaps for point layers. Options include
specifying heatmap radius in pixels, mm or map units, choice of
color ramp, and a slider for selecting a tradeoff between render
speed and quality.
Allows for filling polygons with a tiled raster image. Options
include (data defined) file name, opacity, image size (in pixels,
mm or map units), coordinate mode (feature or view) and rotation.
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).
