Add affine transformation pipeline driver #535
Support for affine transformations would be very beneficial in PROJ.4. For instance it allows users to add simple offset to their coordinates, as requested in #270. It makes sense in many georeferencing applications and could also be used to fit two pointclouds together by applying the reprojection filter in PDAL.
I imagine that it could be used in the following way (inspired by Shapely):
Additionally, users should be able to define their transformation in terms of scale, rotation, shear and translations (although maybe not in the first rendition of this driver).
