Rat-Reloc(ate)

This crate defines the trait RelocatableState

Why?

Many widgets in rat-widget store one or more areas for mouse interaction.

And there are widgets that render other widgets to a temp Buffer and later dump parts of it to the main render Buffer. And then all the stored areas in the widget-state are wrong.

The RelocatableState trait gives the widgets that use such temp Buffers a hook to correct for any movement and clipping that has happened.

Why so complicated?

• This doesn't affect normal rendering of a widget, it's just and afterthought.
• The widget doesn't need to know what other widgets exist, it just has to provide the function to relocate its areas after rendering.
