from estUD to SpatialGridDataFrame in adehabitatMA

Hi,

Before adehabitat was split, I used the function asc2spixdf() to convert
the estimated UD to SpatialGridDataFrame.  I see that there's a
estUDm2spixdf() to convert it to SpatialPixelsDataFrame.  Should the
coercion to SpatialGridDataFrame be done separately in sp?

Cheers,
