Since draw is the only tile operation that we defer, the tile queue can be an array of tiles and queue handling can be simplified. We now use the beforedraw event to defer drawing, and remove all occurrences of a tile from the tile queue when we draw it. Instead of layers that want to defer tile drawing having to override the tile's draw method, layers can now abort drawing by returning false from a beforedraw listener, and later call draw(true) to draw the tile directly, without clearing it first.

Getting OpenLayers
OpenLayers lives at http://www.openlayers.org/. Find details on downloading stable releases or the development version the development site
Installing OpenLayers
You can use OpenLayers as-is by copying build/OpenLayers.js and the entire theme/ and img/ directories up to your webserver and 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/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.
Documentation is available at http://trac.osgeo.org/openlayers/wiki/Documentation. You can generate the API documentation with http://www.naturaldocs.org/: As an example, using bash (with the release files in ~/openlayers):
$ cd ~/openlayers/
$ /path/to/NaturalDocs -i lib/ -o HTML doc/ -p doc_config/ -s Default OL
Information on changes in the API is available in release notes found in the notes folder.
