/******************************************************************************
The following accessible states aren't translated, just ignored:
STATE_READONLY: Supported indirectly via EXT_STATE_EDITABLE
STATE_HOTTRACKED: No ATK equivalent. No known use case.
The nsIAccessible state is not currently supported.
STATE_FLOATING: No ATK equivalent. No known use case.
The nsIAccessible state is not currently supported.
STATE_MOVEABLE: No ATK equivalent. No known use case.
The nsIAccessible state is not currently supported.
STATE_SELFVOICING: No ATK equivalent -- the object has self-TTS.
The nsIAccessible state is not currently supported.
STATE_LINKED: The object is formatted as a hyperlink. Supported via ATK_ROLE_LINK.
STATE_EXTSELECTABLE: Indicates that an object extends its selection.
This is supported via STATE_MULTISELECTABLE.
STATE_PROTECTED: The object is a password-protected edit control.
Supported via ATK_ROLE_PASSWORD_TEXT
STATE_HASPOPUP: Object displays a pop-up menu or window when invoked.
No ATK equivalent. The accessible state is not
currently supported.
STATE_PINNED: The object is pinned, usually indicating it is fixed in
place and has permanence. No ATK equivalent. The
accessible state is not currently supported.
The following ATK states are not supported:
ATK_STATE_ARMED: No clear use case, used briefly when button is activated
ATK_STATE_HAS_TOOLTIP: No clear use case, no IA2 equivalent
ATK_STATE_ICONIFIED: Mozilla does not have elements which are collapsable into icons
ATK_STATE_TRUNCATED: No clear use case. Indicates that an object's onscreen content is truncated,
e.g. a text value in a spreadsheet cell. No IA2 state.
