ProjectiveTransform changes for revisions 24484:24485

This change has been removed. Since the translations and scale factors in a matrix have very different magnitudes, a single tolerance factor is not sufficient. The Apache SIS approach is rather to use double-double arithmetic in matrix operations in the hope to avoid the need for a tolerance threshold.
