[Gegl-developer] API change for samplers to pass inverse Jacobian data to samplers

[Nicolas Robidoux]

Adam:

(Ignore if my last email about GeglMatrix3 was off the mark.)

Is it that affine transformations, stored in 3x3 matrices, get
simplified when they are chained?

If so, where is the final overall 3x3 representation?

Hopefully, extracting the linear part from it to compute the inverse
Jacobian could be done there.
