Which I guess is the same as nearest-neighbor interpolation... I don't know enough about warps to know whether this would be a suitable use for that function, or whether it is more correct to do a proper interpolation for this...\r\n\r\n@sciunto the example is awesome, thanks! I just saw that you haven't finished with the comments so I'll wait till then for further review."}}
