Something related is to have classified label styles. Often it is
necessary to apply multiple label styles in one layer depending on
attribute expressions (kind of rule based renderer for labels).
Maybe in 2.1...<br>

I've been doing for the past week:<br>
<br>
</div>
<div class="gmail_extra">* Label backgrounds (geometric shapes
and SVG) have been implemented/committed, but currently have
a couple of loose ends [0].<br>
<br>
</div>
<div class="gmail_extra">* Label drop shadows are essentially
functional, and work for label buffers [1]. I need a couple
of days to clean up the overly verbose code, simplify the
logic and make it work for label text and backgrounds. In
the GUI and map canvas screen snaps [2][3] you can see an
example of the radius blurring and of the 'global' offset
option (there are also debug rectangles shown). When global
is checked for shadow offset, rotated label's drop shadows
are adjusted to match the global offset for the layer
(instead of being relative to the label's rotation). For
example, this allows all drop shadows on all labels, or
their buffers/backgrounds, to match what a user may have
setup in a hill shaded raster, i.e. opposite the angle of a
virtual sun. Turning on all these features does slow
labeling down, of course. :^)<br>

<div class="gmail_extra">Can I push the cleaned up and
functional labeling drop shadows work to master branch in a
couple of days, for inclusion in 2.0? It was my
understanding this was part of the labeling background work
I was temporarily allowed to do, but it has taken a couple
of days longer than expected.<br>
<br>
</div>
<div class="gmail_extra">Does switching over the data defined
backend for labeling constitute a new feature? If not, I'd
like to work on it over the next week. <br>
<br>
If switching over the data defined backend is considered a
new feature, and not allowed to be committed right now, can
I at least work on adding some of the missing data defined
options for labeling?<br>

<br>
I'd love to have these label backgrounds and drop
shadows in QGIS 2.0.<br>
Makes sense to me to include this work despite feature
freeze since a<br>
major effort was made already to improve labeling in
QGIS 2.0.<br>
<br>
so +1 from my side.<br>
<br>
Thank you for your work, Larry.<br>
