Suggestion: Adding editing tools for photos

[CodingTurtle2]

It would be great if I could edit my pictures, like paint on the picture or resize it, like it is implemented in the ios photo app.

Since editing photos are unfortunately only present in very few apps on linux, this would be a great addition.

If help is wanted and this suggestion itself would be accepted, I would work on a possible implementation and then provide this as a pull request
