Make the widget distribution buttons take into account the widgets' dimensions

[thorsten.langner]

Thats in fact a pain.

I mentioned it here in another topic:

The one with the distribute widgets is one I don’t like, because it behaves weird. When the widgets are not equal sized, the distribution is not for equal gaps (as MS Office behaves) but for equal distance from the top left corners. That makes them partially overlapping and partially having huge gaps…

And I was sure, I posted a screenshot about this somewhere else, but I didn’t find it anymore…

This would be really helpful to make it behave like MS Office (equal gaps…).
