function fb_connect_theme_registry_alter in Drupal for Facebook 7.3

Same name and namespace in other branches

1. 6.3 fb_connect.module \fb_connect_theme_registry_alter()
2. 6.2 fb_connect.module \fb_connect_theme_registry_alter()

Implements hook_theme_registry_alter().

Override theme functions for things that can be displayed using XFBML. Currently overriding username and user_picture. We rename the original entries, as we will use them for users without javascript enabled.

This hook is not well documented. Who knows what its supposed to return? No doubt this will need updating with each new version of Drupal.
