Symmetry diagonal

This plugin is a combination of codes and idea based by code:

- Tin Tran "Fill_rotate.py" https://gimplearn.net/viewtopic.php?f=3&t=1393

Thank you to the coding masters. :hi5

In menu GIMP: Filters->Distorts->Symmetry->Symmetry by diagonal...

The original plugin works without any problems for Gimp 2.10 but for my own needs I modified it a bit

Modified plugin in menu Gimp: Filters->Distorts->Symmetry->Symmetry Tile...

Always thought its something the Inkscape developers made up, but the links says: Quote: The IUC notation is the notation for the symmetry group adopted by the International Union of Crystallography in 1952.
