;; --- Modifiers
;; The `modifiers` structure contains a list of transformations to
;; do make to a shape, in this order:
;;
;; - resize-origin (gpt/point) + resize-vector (gpt/point)
;; apply a scale vector to all points of the shapes, starting
;; from the origin point.
;;
;; - resize-origin-2 + resize-vector-2
;; same as the previous one, for cases in that we need to make
;; two vectors from different origin points.
;;
;; - displacement (gmt/matrix)
;; apply a translation matrix to the shape
;;
;; - rotation (gmt/matrix)
;; apply a rotation matrix to the shape
;;
;; - resize-transform (gmt/matrix) + resize-transform-inverse (gmt/matrix)
;; a copy of the rotation matrix currently applied to the shape;
;; this is needed temporarily to apply the resize vectors.
;;
;; - resize-scale-text (bool)
;; tells if the resize vectors must be applied to text shapes
;; or not.
