[Gdal-dev] Gdalwarp resampling

[Matt.Wilkie]

Hi Frank,
On the page http://gdal.maptools.org/gdal_utilities.html at the end of the
'gdalwarp' section it says:

---------
Mosaicing into an existing output file is supported if the output file
already exists.

It currently has the following limitations:

    * Only 8 bit data is can be warped.
    * The entire source image is held in memory.
    * Only nearest neighbour resampling is available. 
---------

Do these limitations apply only to mosaicking or to all gdalwarp options
generally?

Thanks,

-matt wilkie
