Modifies default settings for editor instances.
Modules that extend the behavior of other modules may use this hook to change the default settings provided to new and existing editors. This hook should be used when changing an existing setting to a new value. To add a new default setting, hook_editor_default_settings() should be used.
The return value of this hook is not cached. If retrieving defaults in a complex manner, the implementing module should provide its own caching inside the hook.
$default_settings: The array of default settings which may be modified, passed by reference.
$editor: A string indicating the name of the editor library whose default settings are being provided.
array An array of default settings that will be merged into the editor defaults.
