Raster layer resample (processing option)

[antti siukola]

Hi!

Should the processing option for raster layer work as described in MS
RFC 4 (MapServer Raster Resampling). The RFC says it's adopted in
MapServer 4.8 but it's not documented in LAYER document.
This PROCESSING line doesn't seem to do anything:

	LAYER
		NAME "layername"
		DATA "/url/to/image.tif"
		TYPE RASTER
		STATUS ON
		PROCESSING "RESAMPLE=BILINEAR"
	END

 Should it?

Cheers!
