Haven't seen any well-tested&stand-alone SVD code with an appropriate license
out there yet :-(
The question is if new transform models should reside in the core
library (like the polynomial/TPS transforms, which makes them programmatically
accessible) or in gdalwarp.
In the latter case, the dependency could be kept fairly peripheral with a
conditional compile.
BTW, weren't there plans for an OpenGL accelerated version of gdalwarp?
Maybe at some point it'll become a stand-alone project (i.e., with separate
build system) anyway...
cheers,
Manuel
