Cel-shaded bus

I've now tried out a cel-shaded style for the bus.

Here I'm using a simple dual-pass shadow-mapped shader (main texture in slot 1, and shadow-map in slot 2).

The method for creating the black outline has been around many years since the days of the original 'Quake' modding communities. I'll document it here at some point for those who aren't aware of how it's done.

Here's an in-game shot from the asset editor.
