hook_theme(). But is there a hook_theme_alter()? I'm looking for something like
hook_menu_link_alter(), which overrides hook menu entries, but for the theme. I want to modify a view hook theme entry so I can specify where to look for one of my custom templates. I am not interested in specifying it through the Views interface, since it look for the theme template inside the theme folder, and I want my template in a feature module.
Which of these keys should I modify in order to make the view pickup the template from the module?
If I put views-data-export-xml-header--richard-feeds-nokia-movies--views-data-export-1 in the feature, the View defaults to pick up views-data-export-xml-header.tpl.php. If I put that template in the theme layer, the view picks it up (even with the registry alter hook in place).
