* gdk/glue/event.c: kill * gdk/glue/selection.c: kill * gdk/Selection.cs: hardcode the primary, secondary, and clipboard atom definitions instead of using glue to access their macros. * gdk/Event*.cs: rewrite to use layout structures instead of glue for field accessors. Also enable writing for all fields. [Fixes #323373] svn path=/trunk/gtk-sharp/; revision=123197
