Adding support for a tileOrigin property to all gridded layers. If working with a cache of tiles that don't align with the bottom left corner of the layer's maxExtent property, set the layer's tileOrigin property. This change also removes the tileExtent property (not in any release), favoring tileOrigin as the way to determine how the grid is aligned. r=ahocevar (closes #3011).
