This effect deforms a path by using four control paths, one for each side of the bounding box. Each control path can be edited individually by clicking on the corresponding icon. When editing of one control path is enabled, that path will be shown in bold green; the other control paths will be shown with thinner green lines in v0.47 (not shown in v0.48). Note that the when copying, pasting, or linking a control path, the control path is referenced from the bottom left corner of the page.
There are options to enabling and disabling the top and bottom paths separately from the left and right paths.
