Comment 3 for bug 380726

three LPE editing regressions related to revision 9038 observed in Inkscape 0.47+devel r9045 (compared to r9029) due to un-checking the new preference
[ ] update path when dragging nodes

* Interpolate Sub-Paths
  - doesn't save trajectory path (parameter)
    works in 0.47, 0.47+devel r9029

* Spiro spline
  - cusp nodes (between straight segments) set to 'smooth' are
    not longer recognized as smooth nodes for Spiro splines
    works in 0.47, 0.47+devel r9029

    steps to reproduce:
    1) node tool preferences: uncheck '[ ] update path when dragging nodes'
    2) pen tool: draw closed triangle with straight lines
    3) node tool: select all -> make selected nodes smooth
    4) apply Spiro spline path effect (fails in r9045)

    expected result: circle through 3 points
    actual result: triangle

    workaround:
    - change cusp nodes to symmetric nodes (not smooth nodes)
    or:
    - node tool preferences: check '[x] update path when dragging nodes'

* Stitch Sub-Paths
  - stitch path is diagonally mirrored when editing
    works in 0.47 (not related to revision 9038)
  - doesn't save stitch path (parameter)
    works in 0.47, 0.47+devel r9029
