Get labels working better with OpenLayers
-----------------------------------------
Key: GEOS-1076
URL: http://jira.codehaus.org/browse/GEOS-1076
Project: GeoServer
Issue Type: Sub-task
Components: Mapbuilder Intergration
Affects Versions: 1.5.0
Reporter: Chris Holmes
Assignee: Andrea Aime
Priority: Critical
Fix For: 1.5.1, 1.6.0-beta1
Labels in the default openlayers preview look like crap. There are two ways to solve this
1) build a mini-metaTiling engine in to GeoServer that uses soft references, under the assumption if there's a request for tiles then there will be similar requests soon. Ideally this would eventually hook up to the full JTileCache. Ideally this can deal with things in different SRSs, but if that's too much work it could just kick in for lat/long, and then use option 2) for the rest.
2) Use an untiled WMS layer in openlayers by default. Could also be nice to make this an additional output format option - you could pass in to GeoServer whether you want a tiled or untiled layer. If you don't have labels the tiled layer may often be preferable.
There is obviously a continuum between 1 and 2. We should probably err on the side of better labels by default, even if they have to be untiled in some cases.
