[Regina Obe] One more thing - sent too soon.
Seems the terminology of using Values is all wrong here as it returns a
Here is a crazy idea which I know you are going to hate cause you hate
overloading functions :)
How about just overloading the name ST_Force3DZ, ST_Force3DM cause that's
essentially what you are doing here isn't it?
Except instead of passing in a numeric to force up, you are passing in a
raster to interpolate the values.
