My first reaction to the thread was to simply add the basic transformation
matrix to the xy side of the proj system but after looking at
http://en.wikipedia.org/wiki/Transformation_matrix
I think the more general affine matrix would be a better final solution.
+xform=[comma separated array of 4 or 6 real numbers]
4 for transform, 6 for affine.
Note that cos/sin values must be precomputed.
I'm somewhat kidding about the affine. ;-)
