+	    shape's *center* rather than a corner, growing symmetrically as
+	    the cursor moves away from it -- the same meaning Ctrl already
+	    has on a Resize handle (anchor at center). Deliberately not
+	    offered for Line: unlike the Rectangle/Ellipse case, there's no
+	    established convention for "a line grows symmetrically from its
+	    middle" to justify it by, so Ctrl for Line means only free
+	    positioning (see the plain grid-snap check above), nothing more.
+	  - Shift, for Rectangle/Ellipse only: forces the bounding box square
+	    (so Ellipse becomes a true circle), using whichever of the two
+	    dragged dimensions is currently larger and mirroring that onto
+	    the other, preserving the direction the user is actually
+	    dragging in.
+	Both can combine (Ctrl+Shift: a centered square/circle). Whether or
+	not Ctrl is currently held, the non-anchored branch always rebuilds
+	from m_anchor_point rather than nudging the existing rect/line --
+	otherwise, if Ctrl had been held earlier in the same drag (moving the
+	shape's own first point to a mirrored position), releasing it would
