Thumbnail service: needed method

[jburel]

I cannot find a ticket for that
For The Viewed By option, i will need to set the pixels and the userID something like
service.setPixelsId(pixelsID, userID).

This is actually key. We need to have the ability to indicate to the thumbnail service
which user the thumbnails are for.
For now I do

 ThumbnailStore service = getThumbService();
needDefault(pixelsID, null);
//getRendering Def for a given pixels set.
if (userID >= 0) {
   RenderingDef def = getRenderingDef(pixelsID, userID);
   if (def != null) service.setRenderingDefId(def.getId());
}
return service.getThumbnailDirect(new Integer(sizeX), new Integer(sizeY));
//return service.getThumbnail(new Integer(sizeX), new Integer(sizeY));

If I use the getThumbnail instead of getThumbnailDirect
The wrong thumbnail is returned from the cache (I guess!) and the settings I passed
seem to be ignored.

r2464 should fix the problem with the cache giving you the wrong thumbnail.
