Yeah, but the step forward here is that the _value_ to burn-in would be
embedded in the point-or-multipoint itself. Rather than burning a constant
into the raster where the vector hits, you'd burn a value that the vector
holds. For points it'd be straightforward, for lines might still do something
smart like linearly interpolating, for polygons I can't imagine anything smart.
