crop tool - Lock Aspect glitch + request

[Peter Wassink]

If you Lock Aspect in the Croptool it respect the aspect when you drag the slider.
But if you type in only the Height it will not do it.
It does display the correct new Width according to aspect in the tool panel itself
but in the HUD interface the Width value is not updated.
And cropping will result in a different Aspect.

When typing only Width it works normal.

And could we also have a "Lock Center" tick box in this menu?
