nx-X11/programs/Xserver/hw/nxagent/Display.c: use new ReconnectTolerance nxagentOption in nxagentCheckForDefaultDepthCompatibility() and modify behavior based on this value.
Recognized values: - Strict means that the old and new default depth values must match exactly. - Safe or Risky means that the default depth values might differ, but the new default depth value must be at least as high as the former default depth value. This is recommended, because it allows clients with a higher default depth value to still connect, but not lose functionality. - Bypass or higher means that all of these checks are essentially deactivated. This is probably a very bad idea. Note that the default ReconnectTolerance value is still Strict.
