More changes and enhancements in accessibility implementations have been migrated from the CWS OO31IA2:

- ButtonDialog: adjust Z-Order for own buttons before showing the dialog (so they are at the end in reading order)
- ImplListBoxWindow::GetBoundingRectangle( USHORT nItem ) - rectangle calculation changed (probably only different when having MRU entries)
- MultiLineEdit: Avoid some unnecessary focus events (compound control)
- Use QuickHelpText as accessible name for different controls when no accessible name exist
- WINDOW_FIXEDLINE: Use role LABEL instead of SEPARATOR when the line has text
- Window::ImplDlgCtrl: Don't grab focus to basic window type on KEY_UP/DOWN/LEFT/RIGHT
- Window::SetAccessibleName: Use GetNonMnemonicString
- accessible check box returns, depending on current state, action check or uncheck, instead of click
- accessible name for scroll bars is "horizontal/vertical scroll bar"
- scroll bar shouldn't have the state focusable
- getForeground shouldn't return COL_AUTO, returning concrete color now
- getNumberingRuleByIndex: return bullet char only if GetNumberingType is SVX_NUM_CHAR_SPECIAL
- listbox notification for focus item changed
- no selection event for tab control itself, tap page will notify
- radio buttons accessible action description is select, not click
- show tabpage before grabbing focus to first widget, so it's not still hidden when sending the focus event
- update accessible name when the doc title changed
- some changes in listbox/treebox events
- charts use role SHAPE now
