trigger_paint_cleanser

Code classes:

• CTriggerPaintCleanser
• CBaseTrigger (triggers)
• CBaseToggle
• CBaseEntity (all ents)

trigger_paint_cleanser is a brush entity present in Portal 2. It erases gel in midair and gel on objects such as cubes. It does not remove gel applied to brushes, or block gel from streaking past it.

Bug: Physics objects are always cleansed, even when the Physics Objects flag is unchecked.

Note: To use gel, the map needs to have Paint in Map set to True in worldspawn. Maps that do not use gel can save significant resources by avoiding touching gel textures and code.
