/**
* This provides ranges, initial values, steps and dropdown menu choices for the
* configuration.
* @remarks
* Checkbox: `boolean`
*   The value supllied will be used as the initial value.
*
* Text field: `string`
*   The passed text will be used as the initial value. Any text will be
*   accepted afterwards.
*
* Number range: `[number, number, number, number]`
*   The meanings are `[initial value, min, max, step]`.
*
* Dropdown: `[Exclude<string, "color">, ...(string | number | boolean)[]]`
*   Translations for people with poor understanding of TypeScript: the first
*   value always has to be a string but never `"color"`, the rest can be any
*   combination of strings, numbers and booleans.
*
* Color picker: `["color", string]`
*   The first value says this will be a color picker not a dropdown menu. The
*   next value is the initial color.
