Uses new gradient editor widget and color controls for easier
manipulation of gradients. Also adds an interactive plot
for modifying gradient stops via the color HSV or RGB values.

A "filled marker" is similar to the simple marker symbol layer, except
that it uses a fill sub symbol to render the marker. This allows use
of all the existing QGIS fill (and outline) styles for rendering
markers, eg gradient or shapeburst fills.
A new abstract class QgsSimpleMarkerSymbolLayerBase has been created
from which both QgsSimpleMarkerSymbolLayerV2 and
QgsFilledMarkerSymbolLayer derive. All common code has been moved to
this base class, allowing for easy addition of new shapes or features
to both simple markers and filled markers without duplication.
Also, adds a lot of missing docs to marker symbol layers.
Using this renderer no symbol will be drawn for features, but labeling,
diagrams and other non-symbol parts will still be shown.
Selections can still be made on the layer in the canvas and selected
features will be rendered with a default symbol. Features being edited
will also be shown.
This is intended as a handy shortcut for layers which you only want
to show labels or diagrams for, and avoids the need to render
symbols with totally transparent fill/border to achieve this.
(fix#12131)
* Move height and angle expressions for 2.5D renderer to layer
* Apply color based on main symbol color
This makes the transition to other renderers easy.
Fixes#14132
This adds a configuration interface and renderer that makes it easy to
put all the pieces together which are required to get a 2.5D effect.
It allow for configuring some of the styling and is meant to create an
easy-to-use setup.
Since every part of the system is built around QGIS' internal rendering
and symbology engine, there is much to fine tune. To get all the
possibilities, just change the renderer to a graduated, categorized or
single symbol renderer upon creation and you will find full access to
improve the style to your needs.

Now all classes and members are either exposed to bindings or marked
as "not available in Python bindings" in the docs.
Drop test thresholds to 0. Now it should be much easier to determine
what missing members have been added which are causing test
failures.
This check tests that if a function has been declared deprecated
with either Q_DECL_DEPRECATED or has a @deprecated Doxygen note
then it MUST have both the Q_DECL_DEPRECATD and @deprecated note.
It's important that both are used, as Q_DECL_DEPRECATED allows
throwing a warning if that method is used in code, while the
@deprecated doxygen note gives an indication to devs/PyQGIS users
of why it's deprecated and what should be used instead.
Ideally we'd also test for SIP /Deprecated/ tags, but I can't
find any reliable way to do this.
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!
This means that symbol selectors can be aware of the correct variable
scope and values for both populating expression builder widgets and
for symbol previews.
Size and Rotation can be defined by an expression for all symbols
composing a marker. Width can be defined by an expression for all
symbols composing a line.
For markers, a legend is generated for varying sizes. This allows
multivariate analysis legend in the case of classified/graduated colors.
The offset is now set along with size to maintain the relative position
of symbols composing a marker.
An asistant, with preview, is accessible through the data defined button
to help the user define the size expression. Three methods are
available: Frannery, Area and Radius.
Added a widget for use in categorized/classified symbology gui to set
the expression if needed. The assistant is also available from it.
This adds a new histogram tab to the graduated renderer, which
shows an interactive histogram of the values from the assigned
field or expression. Class breaks can be moved or added using
the histogram widget.
A base class, QgsHistogramWidget, has been created to display
histograms for a field or expression. In future this could be
used to show a histogram within a "selection statistics" panel.

- enhanced methods for storing/retrieving QgsDataDefined in a
string map
- add method to QgsDataDefinedButton to update parameters for a
QgsDataDefined
- deprecate an unused method
- const correctness
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.
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.
