Feature Request - A more convenient crop

[Olaroll]

Motivation It's nice to crop an image while testing models to shorten the runtime. Currently I'm doing this with the Crop (offsets) node, but adjusting it is a pain.

Description I think the best solution would be a new node that looks like a View image node, but also has an image output. When you drag over the displayed image with your mouse, it would draw a box to indicate where it will crop the image.

This would sorta be implemented by how we're planning on doing an advanced image preview window. Not sure when we'll actually be able to get to that, but we've been talking about the details of it the past couple of days and it will have some sort of crop feedback feature like this
