User feedback: the self-drawn scale handles clash visually with the ImGuizmo translate/rotate rods (different size/style, clearly not one widget). Keep the library widget for all three ops for visual consistency and prevent mis-drags by masking degenerate axes via SetAxisMask: - translate: axis ~ parallel to camera-to-object line (sin < 0.25) - scale: axis ~ perpendicular to camera-to-object line (|dot| < 0.1, intersection numerator identically zero -> grab fails/values jump) OR axis ~ parallel to view direction (|dot| > 0.98, zero screen displacement -> value never changes) - rotate: screen-space math, no degeneracy, no mask Masked axes are neither drawn nor activatable; a slight view change restores them. Center uniform-scale square (MT_SCALE_XYZ, pure screen space) stays available in any view.
