/**
 Custom button to make the large square buttons look nicer,
 with rounded corners and 2px border width, indicate disabled with alpha < 1
 Created on 2021-08-16
 
 Works with many button types.
 The "bordered" property must be off, otherwise the theme drawing will kick in after drawRect and overpaint
