3D results

[gassc]

Get those rainfall results showing in 3D! Need to work-around the transparency issue for pixels with no-data (simply by eliminating those geometries for results, which means separating the results and hover layers in the stylesheet)

Longer term: consider using color and height to represent different things: e.g., DDF for a default return period (or a comparable one if we have an event on record) for color, and height for rainfall
