I want to request small WMS tiles instead of a single image for the entire map viewport because I know the request is going through a Tile Service (TileCache). OpenLayers handles this with the WMS layer by setting singleTile=false. JSAPI has the ability to set the maxHeight and maxWidth via the resourceInfo options attribute.
But the JSAPI does something unexpected but very practical when these values are set. Instead of getting multiple images to fill the map it still gets a single image and stretches it to fill the map (see http://jsfiddle.net/LA2aH/ for an example).
What I appears to be missing is an option to get multiple images.
The reason I'm asking about this is I have a TileCache service which is accessible via a WMS service but the requests must have specific BBOX values.
