Direct Selection showed and dragged the anchors of type on a path's path
(#3980) but not their direction handles: handle_anchors read only a
path's own data, and the canvas draws only a path's handles.
- text.setPathHandle moves a handle of type on a path's path, in
document space, as path.setHandle moves a path's; the brackets keep
their fractions and the text reflows. One undo step.
- Direct Selection draws the handles of selected type on a path and
drags them with it (Alt: one side, Shift: 45 degree steps).
