[OpenLayers-Users] TileCache 1.3

[Christopher Schmidt]

TileCache 1.3 has been released.

With this release comes improved metatiling support. 

 * As Chris Holmes reported, images were being shifted from their 
   previous position by the size of the metaBuffer. This has been fixed.
 * Tim Schaub and Matthew Perry reported problems maintaining
   transparency in palletted PNGs. This has been fixed with a patch from
   Matthew.
 * metaBuffer and metaSize variables were not being properly initialized
   from the configuration. Fixed.
 * Mapnik performance has been improved by caching the Mapnik Map
   object. This means, however, that TileCache requires Mapnik SVN r405
   or later to function correctly.
 * Integrated an additional fix to Windows for writing tiles which
   already exist in the Disk Cache, courtesy of Tim Schaub.
 * Added documentation of all layer params to the README.

Thanks to all the users who reported problems and fixes. 

With this release, metaTiling support is now complete. TileCache is now
used with metaBuffering on to power the OpenStreetMap map at
http://labs.metacarta.com/osm/ (powered by Mapnik). It is my belief that
metaTiling support is now complete and well-tested, and ready for use in 
production.

(As Schuyler might say, <s>maps</s> metaTiles are cool!)
