The Visual C++ project files for GTK+-2.24.x need to be updated as the
Windows theme engine (libwimp) currently has to be built as a DLL.
This adds the Visual C++ 2008 project file to build libwimp as a standalone
module/DLL, and the property sheets, .sln file and gtk.vcprojin are updated
accordingly so that the needed stuff get built properly and go to the
proper places for the Windows Themes to work correctly with the Visual C++
builds.
Thanks to nus for pointing this out. Visual C++ 2010 projects files will
be updated in the next 1-2 days.
Since GDK-Pixbuf is now in a package of its own, stop the distribution
of GDK-Pixbuf projects (those files are no longer referenced in the
GTK+ solution file already)
