Add option for separate tile graphic vs. popup graphic

[swashbuck]

Subject of the enhancement

When using the grid layout, only one graphic option is supported. It would be useful if we could supply a separate graphic for the popup. This would allow us to use a graphic of a different aspect ratio or just a different graphical concept entirely.

As _graphic is currently used by both the pin and grid layouts, maybe a new option for _graphicTile could be introduced?

Examples

This would use a different graphic for the first item's tile and popup image. Note the different aspect ratios. Currently, this is not possible.

Hi @swashbuck,

Perhaps this request would be more fitting for the adapt-hotgrid plugin as it already supports different image paths for the item and the pop up.

We'd need to add a config option to the hotgrid to support a tile based design but that should be mostly limited to styling.
