 the action wp_admin_css is triggered when embedding several css files.
 this behaviour is described in the
 [http://codex.wordpress.org/Creating_Admin_Themes#Change_Log-
 In_page.27s_style codex].

 This means, if you want to override one admin stylesheet, you have to
 override them all, because there is no easy way of finding out which one
 is currently being replaced inside the callback.
 This adds load to the page, because you have to include e.g. upload.css in
 every admin page that is delivered to keep the layout intact!

 So, this action should be split up into several actions, one for each
 stylesheet; or a parameter specifying the stylesheet being replaced could
 be introduced to the callback prototype. (the former maybe being less
 compatibility-breaking by leaving the wp_admin_css action as it is and
 introducing wp_admin_css_main, wp_admin_css_upload, wp_admin_css_login
 etc.)
