This change makes the current atlas feature (and additionally all
attributes of related child features) available to the source of
a composer HTML item, allowing the item to dynamically adjust
its rendered HTML in response to the feature's properties. An
example use case is dynamically populating a HTML table with
all the attributes of related child features for the atlas
feature.
To use this, the HTML source must implement a "setFeature(feature)"
JavaScript function. This function is called whenever the atlas
feature changes, and is passed the atlas feature (+related attributes)
as a GeoJSON Feature.

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.
A new "legend" tab has been added to diagram properties, allowing
both the existing attribute legend and a new size legend to be
enabled/disabled. The size legend has a configurable marker
symbol.
Also includes unit tests for both diagram attribute and size
legends.

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)
Now labels and HTML boxes can contain relative URLs. If we don't have
a base URL, the project file will be used as a base URL (closes#7236).
Remove the exception for the labels where the images where not
loaded (unless in in PDF or image mode). It was because of a crash. Qt didn't
like having the HTML loading to be done synchronously during painting.
Fix a leak when rendering labels.
label font and margins when rendering as HTML.
This allows interactive choice of font, margins and colors and
avoids the need to manually set these with CSS within the
label HTML code.
This makes it possible to change SVG fill/outline color and outline
width when using parameterised SVG files such as those included
with QGIS (fix#10542)
The raster blend mode test, which uses QgsMultiBandColorRenderer
fails occasionally for no obvious reason. This additional test
is an attempt to narrow down whether the issue lies in
rendering multi band images or elsewhere.
* 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
