It is in twice. I know. I only don't know how to include it correctly from one 
location. If you'd could be so kind and remove one of them that would be great.

I guess there is some rounding error somewhere. if i set the alpha to 0/1 instead of 
[0;1] i see very strange movement. Maybe if i find this "bug" a coarser 
granularity would look fine, too.

interested :)
so some kind of drawAlphaLayer(float ** heightMap, Color color, 
coordX,coordY,cellsW,cellsH,cellsSize)
