Comment:

 As ST_Resample behaves the same way as GDAL gdalwarp utility, this latest
 change maintains that behavior.  gdalwarp does not permit specifying scale
 and width/height at the same time.

 http://gdal.org/gdalwarp.html

 Look at switches -tr and -ts.

 You can only have one or the other as they're dependent upon one another.
 Using GDAL's suggested extent for the warped raster, you can compute the
 dependent variable.  If width/height is provided, the scales are computed
 for the suggested extent.  If scale is provided, the width and height are
 also computed.
