NumberSpinner support for dynamic layout.

Discovered in phetsims/fourier-making-waves#250 ...

NumberSpinner does not support dynamic layout. Like NumberControl, it should probably extend Sizable and resize its NumberDisplay accordingly. (And does dynamic layout also need to be added to NumberDisplay?)

This is not blocking for phetsims/fourier-making-waves#250.

Assigning to @jonathanolson, since he added dynamic layout to most of the other common-code UI components, so is probably most familar with this.

@jonathanolson Can you provide an estimate on how difficult this is, and when it might be available? We're evaluating for phetsims/fourier-making-waves#247.

I'm not particularly familiar with NumberSpinner. It looks like uses a very imperative one-time setup for layout, and it seems to sport a lot of layout options:

So it already looks to be a fairly high-cost thing to understand/rewrite a good number of layouts.

Also, would it resize the NumberDisplay? I thought NumberDisplay was specifically designed as a fairly fixed-size component.

For me to do it would be a good amount of work. Perhaps for this, it might make more sense for me to bring @pixelzoom or someone more familiar with the uses/needs up to speed on the approaches used in other components.

Thanks for the info @jonathanolson. We'll punt on this for phetsims/fourier-making-waves#250, and discuss next steps via the Developer Priorities board.
