If not I believe a useful feature would be to provide the resourceInfo maxHeight, maxWidth as well as a new attribute (maybe stretchTile or singleTile).
stretchTile = false implies that instead of the default behavior of stretching a tile to fill the map you instead get one or more tiles to fill the map.
The trade-off would be no loss in resolution vs multiple trips to the WMS service.
USE CASE The reason I request this functionality is for integration with tile servers, specifically TileCache. TileCache expects the WMS bbox to correspond to a tile.
