From 29fa4ed9f00507e3056210b5e72447659d66b881 Mon Sep 17 00:00:00 2001 From: aliguori Date: Mon, 2 Feb 2009 15:58:29 +0000 Subject: Use VNC protocol defines (Alexander Graf) Now that we have nice defines for all sorts of constants, let's use them! This patch also takes the "feature variables", currently called has_* into a single feature int. This way adding new features is a lot easier and doesn't clutter the VncState struct.
