DecalManager not in proper scene container

[DavidWyand-GG]

There is an issue with the DecalManager not being put into the correct scene container, which is known as the overflow bin for global objects like this. It had to do with its bounds not being set up correctly before being added to the client scene graph. However, I believe that the correct fix is to change the logic in SceneContainer::insertIntoBins() to completely ignore the object bounds when the object has been explicitly set as a global one.

The discussion of this issue and a possible fix may be found in the following forum post:
