- The libcef project now builds libcef_static.lib instead of libcef.lib. - The libcef_dll project builds libcef.lib and libcef.dll. This DLL exports the new CEF C API defined in cef_capi.h, cef_nplugin_capi.h, cef_string.h and cef_string_map.h. - The libcef_dll_wrapper project builds libcef_dll_wrapper.lib. This static library wraps the new C API calls with an implementation of the CEF C++ interface as defined in cef.h and cef_nplugin.h. - The cefclient project now uses the DLL instead of the static library. - Type definitions have been moved from cef.h to cef_types.h so that they can be shared by both cef.h and cef_capi.h. This change required some enumeration member name modifications throughout the code base. - Fixed variable naming inconsistencies. - Added CefVariant::GetArraySize() method and _NPN_ArrayObjectGetVectorSize() function. - Remove the ProjectSection(WebsiteProperties) sections from cef.sln to improve VS2005 performance. git-svn-id: https://chromiumembedded.googlecode.com/svn/trunk@16 5089003a-bbd8-11dd-ad1f-f1f9622dbc98
