 With an 'affine' type, it would be possible to create some cool affine
 utilities
 {{{
 ST_AffineCalculate(point, point) => affine (translate)
 ST_AffineCalculate(line, line) => affine(scale/rotate/translate/shear)
 ST_AffineTranslate(affine, point) => affine with added translation
 ST_AffineRotate(affine, angle) => affine with added rotation
 ST_AffineScale(affine, point) => affine with added scale
 ST_AffineInvert(affine) => affine the carries out reverse of input
 }}}
