Env bubbles

env_bubbles in game, with density set to 35 and frequency set to 20.

Template:Base brush It is used to create a volume in which to spawn rising bubbles. The number and frequency of bubbles can be adjusted.

env_bubbles is obviously intended for use in water, but it can be used outside of water if such an effect is desired.

In code, it is represented by theCBubblingclass, defined in theeffects.cppfile.

Bug:Doesn't work in Portal 2 with any tool texture. Tying a toolstrigger brush to this entity will result in the entity being rendered in-game as a raw brush of said material.  [todo tested in ?]
