Disable error messages for IR?

[maru]

Maybe the error messages could be disabled for IR only? They are a bit annoying when they pop up every time you move camera/object. They would pop up anyway for regular rendering, so it wouldn't be so "risky". ;)

Some messages are now not displayed more than once, so that should help. If you have any specific messages that should not be displayed in IR in mind, then post them, but generally I would like to keep them
