[flexcomponents] How to determine the minimum container size while scroll bars still not needed

[Sergey Kovalyov]

Hi All!

There is mx_internal::getScrollableRect() method and the value it returns
does not change when you make the container smaller at some moment when
scroll bars appears.

But I need to know those values at any given time.

Finally what I want to achieve is to have resize handle in the right bottom
corner that allows to resize the container, but does not allow to make it
smaller than the size when all children fit and no scroll bars are needed.

Any ideas?

Sergey.
