Title: Don't draw singleTile WMS layers outside of the layer's maxExtent

Don't attempt to draw an adjusted singleTile wms request when it falls fully outside of the layer's maxExtent.

Adds to issue addressed by #304, which didn't account for bounds fully outside of the layer's maxExtent and attempts to request a tile with bad bounds and negative tile widths or heights in that case.
