;; -- temporary modifiers -------------------------------------------
;; During an interactive transformation of shapes (e.g. when resizing or rotating
;; a group with the mouse), there are a lot of objects that need to be modified
;; (in this case, the group and all its children).
;;
;; To avoid updating the shapes theirselves, and forcing redraw of all components
;; that depend on the "objects" global state, we set a "modifiers" structure, with
;; the changes that need to be applied, and store it in :workspace-modifiers global
;; variable. The viewport reads this and merges it into the objects list it uses to
;; paint the viewport content, redrawing only the objects that have new modifiers.
;;
;; When the interaction is finished (e.g. user releases mouse button), the
;; apply-modifiers event is done, that consolidates all modifiers into the base
;; geometric attributes of the shapes.

;; -- Temporary modifiers -------------------------------------------
;; During an interactive transformation of shapes (e.g. when resizing or rotating
;; a group with the mouse), there are a lot of objects that need to be modified
;; (in this case, the group and all its children).
;;
;; To avoid updating the shapes theirselves, and forcing redraw of all components
;; that depend on the "objects" global state, we set a "modifiers" structure, with
;; the changes that need to be applied, and store it in :workspace-modifiers global
;; variable. The viewport reads this and merges it into the objects list it uses to
;; paint the viewport content, redrawing only the objects that have new modifiers.
;;
;; When the interaction is finished (e.g. user releases mouse button), the
;; apply-modifiers event is done, that consolidates all modifiers into the base
;; geometric attributes of the shapes.
