The text format conditionally sets values for feature.style.graphicXOffset and graphicYOffset. If these are not defined in parsing, we confirm that using the non-identity operator with undefined. Later, it might make sense to confirm these values are actually numeric (see #1441). This keeps an icon.offset from inadvertently getting created with NaN values later on. r=elemoine (closes #1571)
Adding support for TextSymbolizer writing in the SLD format. Thanks to Bart for the original patch. This provides basic expression handling for text labels. Read support later. r=ahocevar (closes #1542)

Getting OpenLayers
------------------
OpenLayers lives at http://www.openlayers.org/.
You can get OpenLayers from
http://trac.openlayers.org/wiki/HowToDownload.
---------------------
Installing OpenLayers
---------------------
You can use OpenLayers as-is by copying build/OpenLayers.js and the
entire theme/ and img/ directories up to your webserver, putting them
in the same directory. The files can be in subdirectories on your website, or right in the root of the site, as in these examples. To include the OpenLayers library in your web page from the root of the site, use:
<script type="text/javascript" src="/OpenLayers.js" />
As an example, using bash (with the release files in ~/openlayers ):
$ cd /var/www/html
$ cp ~/openlayers/build/OpenLayers.js ./
$ cp -R ~/openlayers/theme ./
$ cp -R ~/openlayers/img ./
If you want to use the multiple-file version of OpenLayers (for, say,
debugging or development purposes), copy the lib/ directory up to your
webserver in the same directory you put the img/ folder. Then add
the following to your web page instead:
<script type="text/javascript" src="/lib/OpenLayers.js" />
As an example, using bash (with the release files in ~/openlayers ):
$ cd /var/www/html
$ cp -R ~/openlayers/lib ./
$ cp -R ~/openlayers/theme ./
$ cp -R ~/openlayers/img ./
------------------------------------
Using OpenLayers in Your Own Website
------------------------------------
The examples/ directory is full of useful examples.
Dcumentation is available in the doc/ directory: to build an HTML version
of the documentation, run ./docs.sh in the build/ directory.
Information on changes in the API is available in news.txt.
