Subject: [PATCH] New nodes: 'Gradient Type' and 'Spread Method', and add
 Gradient tool support for controlling these nodes (#4084)

* Use 'Transform', 'Gradient Type', and 'Spread Method' nodes for table gradients

* Add gradient widget to the tool's control bar and update where the two swap buttons go

* Fix gradient rendering

* Format

* Code review
