app: add custom GUI for gegl:recursive-transform-plus
gegl:recursive-transform-plus is an extension of gegl:recursive-transform, allowing multiple transformations to be applied simultaneously; it will eventually be merged back into gegl:recursive-transform. See GEGL commit 9829bc22e85526d789c4e80c05949d4c6202a207. The GUI uses the new TRANSFORM_GRIDS controller, allowing adding, duplicating, and removing transformations, and controlling them through on-canvas transform grids.
