- Add v8_snapshot_cc project dependency (Issue # 11, fix by: vridosh) - Fix possible crash on exit in browser_resource_loader_bridge.cc (Issue # 12, fix by: vridosh). - localized_strings project renamed to webkit_strings. - GetBitmapResource() in browser_webkit_glue.cc now returns GlueBitmap* instead of GlueBitmap. - GetLocalizedString() in browser_webkit_glue_win.cc now returns string16 instead of std::wstring. - Add BrowserWebViewDelegate::SetStatusbarText() method. - Move BrowserWebViewDelegate::DidMove() from browser_webview_delegate.cc to browser_webview_delegate_win.cc. - Move FromWindow() predefine in webwidget_host out of the header file. git-svn-id: https://chromiumembedded.googlecode.com/svn/trunk@15 5089003a-bbd8-11dd-ad1f-f1f9622dbc98
