High Contrast Gridded Terrain Mods

[Copper]

I was going to do one last mod for Topo Gridded Winter Roads, but the winter road bitmaps actually cover very little of the underlying tile. And the most important part of the tile for seeing elevation changes, which is the exact center of the tile where all the lines meet, is visible in all cases.

Therefore, the current set of files at CMMods completes the Topo Grid series. I hope everybody enjoys them as much as I do.
