2017-02-28Avoid crash above CFWL_ListItem::GetText()Tom Sepez
The issue at hand is caused by a raw pointer rather than a retained pointer in InheritedData::m_pFontFamily. But the larger issue is that it's bad to Get() raw pointers from these, especially when its so cheap to pass them by const reference. One reason to Get() a raw pointer is to aid in down-casts, so add a helper to CFX_RetainPtr to give us downcasted retained pointers.
