Hi Gerd,

I'm trying to get DEM looking like in Garmins img. The actual rounding 
in code can be disabled, but then it would be up to user, to set correct 
distances. I don't know, if rounding is important. Maybe some devices 
need it?

This looked like an easy way to get HGT without computing and comparing 
values for all layers. It could be done better, if the idea fo this 
patch worked out.

Sorry about tests, I don't know how to execute them.

Now I consider to add bicubic interpolation, like this code:
