3	* WordPress scripts and styles default loader.
4	*
5	* Several constants are used to manage the loading, concatenating and compression of scripts and CSS:
6	* define('SCRIPT_DEBUG', true); loads the development (non-minified) versions of all scripts and CSS, and disables compression and concatenation,
7	* define('CONCATENATE_SCRIPTS', false); disables compression and concatenation of scripts and CSS,
8	* define('COMPRESS_SCRIPTS', false); disables compression of scripts,
9	* define('COMPRESS_CSS', false); disables compression of CSS,
10	* define('ENFORCE_GZIP', true); forces gzip for compression (default is deflate).
11	*
12	* The globals $concatenate_scripts, $compress_scripts and $compress_css can be set by plugins
13	* to temporarily override the above settings. Also a compression test is run once and the result is saved
14	* as option 'can_compress_scripts' (0/1). The test will run again if that option is deleted.
