When adding an object to a client's screen, if the object has mouse_opacity set to 0 and the displace filter attached, atoms on the client's screen will no longer register mouse-hits.
Numbered Steps to Reproduce Problem:
1. Download / extract source.
2. Run the source.
3. Mouse over turf or player to see maptext of atom's name.
4. Click the 'MapOnly' verb in the commands tab.
5. Mouse over the turf or player.

Expected Results:
Maptext will continue to display despite the map being present.
Actual Results:
Maptext is not displayed when the map is present.
Does the problem occur:
Every time? Or how often? Every time.
In other games? In my main game, LifeRP.
When does the problem NOT occur? When the displacement filter is removed from the object, atoms react as expected.
Did the problem NOT occur in any earlier versions? If so, what was the last version that worked? The issue was present in 513.1542 and 514.1589.
Workarounds: Unsure, I tried tweaking the object's alpha but didn't gain much ground there.
