[gdal-dev] Transformer from & to Control Points in Map CS

I wondered if anyone may help me understand how to accomplish this with GDAL (Python API preferred):
I would like to create a custom Transformer, based on control points which associate (map_x1, map_y1) with (map_x2, map_y2). The projection is the same for both sets of points.
This transformer needs to transform point coordinates, although ideally I could warp raster data as well. I would like to use TPS or cubic interpolation.
What is the best way to do this?
Will the standard GCP transformer work? I understand it expects GCPs that associate (image_x, image_y) with (map_x, map_y).
