Tested with a release binary and Swiss OSM roads in PostGIS at several zoom
levels (the higher, the less features), values in ms (average over at
least 100 queries):
Level | Before | After | % improvement
-------------------------------------------
7 | 37 | 36 | 2.7
6 | 41 | 38 | 7.32
5 | 48 | 46 | 4.17
4 | 70 | 64 | 8.57
3 | 114 | 109 | 4.39
Not much improvement (I'm quite dispointed, here), but not much change in
the code.
A new checkbox has been added to the legend settings to control
whether or not a legend should be automatically resized to fit
its contents.
If unchecked, then the legend will never resize and instead just
stick to whatever size the user has set. Any content which
doesn't fit the size is cropped out.

When a legend was set to filter content by map, it wasn't
consistently being resized to fit the legend contents. This caused
issues for atlas exports where legends could grow but never
shrink.

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.
