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)
Also includes handy function for converting a string to a QgsFeatureList
or QgsFields by using OGR to parse the string. This allows eg conversion
of GeoJSON to QgsFeatures.
In the OGR provider, we can read:
```
Some ogr drivers (e.g. GML) are not able to determine the geometry type of a layer like this.
In such cases, we use virtual sublayers for each geometry if the layer contains
multiple geometries (see subLayers) otherwise we guess geometry type from first feature
```
It means that in DescribeFeatureType Geometry element can be describe as simple and the GML contains
simple and multi. It's not XML valid.
To fix it, for OGR provider Geometry element type is set to `gml:GeometryPropertyType`
For the next release, it will be interesting to allow users to specify whether the geometries are multi.
