(terrain)Texture splatting

Since there have been popping up a zillion posts about texture splatting and terrain texturing I have added two tests to jME which does simple non-shader multipass texturesplatting, with the use of jME's PassNode.

The tests are TestTerrainSplatting and TestIsland. Both does the same splatting with 6 passes(5 groundlayers and 1 lightmap). TestIsland is the same as TestTerrainSplatting but adds our watereffect and a skybox, to show a more complete use or those together.

Many thanks to Jadestone for letting us use their data from the Spirits demo(though heavily downsampled not to explode our data jars, so it doesn't look as good offcourse)


Awesome  :slight_smile:
