***Note from Migration:***
Original Title was: surface modeller / rasterDEMgenerator - allow attributes to populate output dem x/y cell spacing parameter
it would be extremely helpful in my workflow if i could use an attribute value to populate the output dem xy cell spacing parameter, i'm using python to extract this information out of the raster@ a specific byte, so i've got them as attributes. Right now it only accepts a parameter or a number.
