No, you're working with a property that is meant to be specified at 
construction.  We should document this as read only.

Without resizing your map viewport, there is not a clean (API supported) 
way to change from singleTile false to true.

Layers are cheap, create a new one (or, if you must, call 
layer.clearGrid() and layer.setTileSize() - but be prepared to have 
things break with future upgrades).
