Core should know which locales are RTL
|Reported by:||nacin||Owned by:||nacin|
Currently an RTL locale needs to specify $text_direction = 'rtl'; in a $locale.php file. In the interest of eliminating the need for $locale.php files, core should keep a list of RTL locales.
$text_direction would remain functional, and we're not killing $locale.php -- just trying to cover its primary uses.
While a simple array of RTL locales can be maintained now, there might reach a point where it will be easier to include locales/locales.php in core. (Indeed, mu_dropdown_languages() would benefit from this.) In that case, RTL could be read from there.
