Cursor not kept in view when entering multiple lines of text

To reproduce:
- Create a Text field with SWT.MULTI | SWT.V_SCROLL
- Launch on an iPad/iPhone with the native client
- Enter multiple lines of text using CR after each one until the screen is full

Result: cursor will be below virtual keyboard. Input not visible

Expected: text field should scroll so that cursor & input remains visible (compare with Apple's Notes app). Same issue is also reproducible in mobile Safari.
