[gdk-pixbuf] build: Add Common Autotools Module for MSVC Projects

    build: Add Common Autotools Module for MSVC Projects
    
    This adds a common autotools module that can be used by various
    projects to generate the Visual Studio projects as needed, and
    if necessary, generate the headers listings to "install" for that
    project, based on items passed in to this.  This is modelled on the
    Makefile.introspection autotools file that is used by many GNOME
    projects to generate the introspection files.

+# Author: Fan, Chun-wei
+# Common Autotools file used to generate Visual Studio 2008+
+# Projects from their templates
+
+# This autotools file, from GLib, can be used in other projects
+# that have Visual Studio build support, and is copied into
+# $(srcroot)/build/, except those that have their main sources
+# in their $(srcroot), or those that have their autotools build
+# files in $(srcroot).  Those that should not use this include:
+# gobject-introspection, librsvg, instead they would currently
+# need a modified version of this.
+
+# * Input variables:
+#
+#   MSVCPROJS - List of Projects that should be generated
+#
+# * Simple tutorial
+#
+# Add this to Makefile.am where your library/program is built:
+#   include $(top_srcdir)/build/Makefile.msvcproj
+#   MSVCPROJS = YourProject (can be multiple projects in a single srcdir)
+#   YourProject_FILES = $(libyourlib_1_0_SOURCES)
+#   YourProject_EXCLUDES = ... # list of sources to exclude, separated by '|', wildcards allowed; use random 
unsed value if none
+#   YourProject_HEADERS_DIR = $(libyourlibincludedir)
+#   YourProject_HEADERS_INST = $(libyourlib_1_0_HEADERS)
+#   YourProject_HEADERS_EXCLUDES = ... # <list of headers to exclude from installation, separated by '|', 
wildcards allowed; use random unsed value if none>
+#
+#   dist-hook: \ # (or add to it if it is already there, note the vs9 items will also call the vs10 items in 
the process)
