Crop never returns an error

Looking through the Crop function, it looks as though it never calls a method which would return an error.

It'd be nice if the Crop method did not have a signature which suggests otherwise.

Even better if it did some boundary checking and did return an error. It's possible to try to crop an image outside the dimensions which just returns an 0x0 image.
