Make CFWL_WidgetMgr{Delegate} inherit from IFWL_WidgetMgr{Delegate}.
C-style casting masked a fairly serious botch, where an CFWL_ type would get cast to an IFWL_ type, and later we'd invoke virtual methods against the IFWL_ type. Without the proper inheritance, there's no reason to believe that the vtables for each of these would line up with each other. Fixing the inheritence allows us to remove the c-style casts. I'm guessing these were added to make this compile without having to understand the true nature of the flaw. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1439093003 .
