+Subject: [PATCH] Fix build with glib 2.67.3.
+
+As of glib 2.67.3, <glib.h> can no longer be included in extern "C"
+blocks. It was indirectly included by both "types.h" and "color.h".
+"types.h" already does not need to be wrapped in an extern "C" block,
+"color.h" does but can be modified not to, so with that changed they can
+be moved out.
