A River Runs Through It

Since I wanted a river and bridge in the first map for Alpha Quest, I had to make it possible to make water. I needed to rewire the drawing routines to provide groups for both opaque and transparent surfaces, as well as provide a property on the BuildableMesh that lets me know the Material is transparent. In WPF, the transparent Materials need to be added to the scene graph later than opaque materials so that the opaque materials show up correctly.

This image also shows (in not too much detail) some use of the PanelSpace in the bridge and soil/grass cells on the far bank of the river. It also shows a little bit of very rough shadow in the river bed itself.
