Description
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

Can it be made compatible with opengl matrices?
Would be cool to have a chain of functions that can take screen geometry and camera view and transform both into a shape that ST_Intersects with everything that needs fetching into screen, although it needs some more thought.

I think doing a projection from 3-space to x/y is possible, with a normal to the screen, a normal to the projection plan and a camera locations/direction. But… I'm not sure how useful it would be
