i.vpoints uses the CRS_ version, which supports higher-order
transformations.

Note that i.rectify and i.vpoints each have their own private copy of
the CRS_ code, which is also the same code that GDAL uses for
GDALGCPTransform() etc (alg/gdal_crs.c).

Should the imagery modules use GDAL directly, or should we add an
interface in lib/imagery/georef.c?
