Full terrain support

I feel voxels, in general, are quite limiting, I believe there should be a dedicated terrain tool with a mesh that can be easily edited. Tools should be like in any other terrain editing tool; Raise or Lower Terrain, smooth height, etc. You should be able to use these tools with a variety of stamps, which should be imported as pixelmaps, which would allow more realistic creation of mountains and various other landforms. It would also be nice to be able to import and paint (onto the terrain) my own textures for terrain and voxels.
