Usability on small screens review

[KatieWoe]

Per @kathy-phet's request in phetsims/qa#295 I am making issues in each published sim repo detailing the pointer areas and usability of sims on phone sized screens. Done on an iPhone 7 iOS 12 device.

Potential Difficulties Noticed:

• Add and Remove Wall button pointer area much too small

Screenshots:

Thanks @KatieWoe. This looks like a bug to me. @jessegreenberg can you investigate?

This looks familiar I wonder if this was actually fixed elsewhere recently. @KatieWoe was this screenshot taken off of master or the published version on the website?

[jessegreenberg]

This was already fixed as part of #439. Scenery doesn't allow touch/mouse areas that are smaller than the button which is why the button is still clickable. @KatieWoe can you please confirm that this is fixed in master? @arouinfar is there anything else to do for this issue?

Does seem fixed on master @jessegreenberg

Looks good to me @jessegreenberg, thanks!
