how to resize in horizontal and vertical axis?

[bboyle]

Screenshot above from the demo site: https://stackblitz.com/edit/image-cropper?file=src%2Fmain.ts

The cropper has 8 handles (squares) for resizing.
The 4 corners work by resizing diagonally, as I would expect.
The 4 middle handles I would expect to size on that center axis.

I drag the top-middle handle downwards, I would expect the cropped area to shrink by moving the top border down and the left and right sides in by equal amounts. Instead, the top-middle handle behaves exactly the same as the top-right handle.

Is there a setting to change this behaviour, or is it a bug? need a PR? thoughts?

ps: this aside, it's a great component! thanks for publishing it :)
