function webform_checkbox_prerender in Webform 6.3

Helper function to ensure that the default value of "0" checkboxes renders.

The default handling of checkboxes only checks checkboxes based on the #value property. If a checkbox has a value of "0" (as a string), the checkbox doesn't print out the way it should.
