Yes it does.

It would be good I think to use the GDAL warp API to do the hard work.
Much of it is the same code as GRASS uses with the difference that the
GDAL code is better maintained and more featureful (eg thin plate
splines). GRASS now depends on GDAL, so versioning issues aside this
should be possible.
