I'd rather say there's no hard-coded limit ;-) But the processing time will 
increase with the number of GCPs: linearly when applying the result of the GCP 
adjustment for each point transformed, and with an initial computation cost of 
the adjustment coefficients that has a complexiy a bit below O(n^3).
