GRASS ALWAYS resamples as follows: go to the center of the grid
cell for the current region, compute the coordinates, find the
grid cell that contains these coordinates, look in the map and
extract the value in that grid cell and that value represents the
value for the "output" grid cell for the current region.
Well, I'm glad that it works this way and that my first assumption was
wrong, because this is the way I like it to be. This will open up some
new possibilities for me.
Is the resampling that d.rast is doing from the cell file to the screen
pixels working the same way ?
