Image Class cropping with Rect2

[Theklo-Teal]

Currently the Image class, meant to manipulate the native image datatype contains the function void crop(width: int, height: int) I suggest that the argument should be a Rect2, or otherwise width, height, x, y, or even x_start, y_start, x_stop, y_stop. This would allow to crop the center of a picture, for example.

Would have to be named differently as overloading is not supported, but the simple workaround is:

my_image = my_image.get_region(my_rect)

It's not as efficient and doesn't update other copies though
