Fix WM_IME_ENDCOMPOSITION in Eclipse SWT

Fix Bug 450182

Correctly handles WM_IME_ENDCOMPOSITION message by firing a COMPOSITION_CHANGED event containing empty composed text and empty committed text.

---

Modify org.eclipse.swt.win32

org.eclipse.swt.widgets.IME

Under method WM_IME_ENDCOMPOSITION(), change the code:

from:

LRESULT WM_IME_ENDCOMPOSITION (long /*int*/ wParam, long /*int*/ lParam) {
    return isInlineEnabled () ? LRESULT.ONE : null;
}

to:

LRESULT WM_IME_ENDCOMPOSITION (long /*int*/ wParam, long /*int*/ lParam) {
    if (isInlineEnabled())
    {
        if (text.length() > 0)
        {
            Event event = new Event();
            event.detail = SWT.COMPOSITION_CHANGED;
            event.start = startOffset;
            event.end = startOffset + text.length();
            event.text = "";
            caretOffset = commitCount = 0;
            text = "";
            ranges = null;
            styles = null;
            sendEvent(SWT.ImeComposition, event);
            startOffset = -1;
        }
        return LRESULT.ONE;
    }
    return null;
}
