Jetpack-specific elements of Infinite Scroll
action_after_setup_theme() : null
Load theme's infinite scroll annotation file, if present in the IS plugin.
The setup_theme
action is used because the annotation files should be using after_setup_theme
to register support for IS.
As released in Jetpack 2.0, a child theme's parent wasn't checked for in the plugin's bundled support, hence the convoluted way the parent is checked for now.
