Cogl, when built with the SDL winsys, will include the SDL headers when
Cogl-based programs are built, which causes the SDL's wrapper for main()
to be used on Windows, causing an implicit requirement that all Cogl-based
apps must link to SDL2.lib and SDL2main.lib. Avoid this behavior by
defining SDL_MAIN_HANDLED in the CFLAGS of the sample and interactive test
programs
Like the Visual Studio 2008 projects, give the Visual Studio 2010 projects
an overhaul, where:
-The property sheets are split up, so that they are easier to maintain and
each project only needs to include the necessary parts. The various
projects are updated accordingly, too. The copying of config.h.win32 and
clutter-config.h.win32(_GDK) are now done with custom build rules, so that
these files can be cleaned and/or recopied during a clean, rebuild or
update.
-Clean up the property sheets, to get rid of parts that are actually
repeated. Also update the build macros, so that we won't get warnings
for repeated #defines of macros and fix the build of the various tests/
demo programs.
-Make all projects use Unix line endings, except for the .sln and
README.txt files, which need to have Windows line endings. This makes it
easier to apply patches to these project files.
-Update the installation of headers, as headers are introduced/deprecated.
-Cosmetics: get rid of "\ No newline at end of file".
