 * @eventType	flash.events.IMEEvent.IME_COMPOSITION
 * [Event(name="imeComposition", type="flash.events.IMEEvent")]

 * The IME class lets you directly manipulate the operating system's input method
 * editor (IME) in the Flash runtime application that is running on a client computer. You can
 * determine whether an IME is installed, whether or not the IME is currently enabled, and which IME is
 * enabled. You can disable or enable the IME in the application, and you can perform other limited
 * functions, depending on the operating system.
 *
 *   <p class="- topic/p "><i class="+ topic/ph hi-d/i ">AIR profile support:</i> This feature is supported
 * on desktop operating systems, but it is not supported on all mobile devices. It is also not supported on
 * AIR for TV devices. You can test for support at run time using the
 * <codeph class="+ topic/ph pr-d/codeph ">IME.isSupported</codeph> property. See
 * <xref href="http://help.adobe.com/en_US/air/build/WS144092a96ffef7cc16ddeea2126bb46b82f-8000.html"

 * <p class="- topic/p ">IMEs let users type non-ASCII text characters in multibyte languages
 * such as Chinese, Japanese, and Korean. For more information on working with IMEs, see the
 * documentation for the operating system for which you are developing applications.

 * If an IME is not active on the user's computer, calls to IME methods or properties,
 * other than <codeph class="+ topic/ph pr-d/codeph ">Capabilities.hasIME</codeph>,
 * will fail. Once you manually activate an IME, subsequent ActionScript
 * calls to IME methods and properties will work as expected. For example, if you are using a
 * Japanese IME, it must be activated before any IME method or property is called.</p>
