This is the base class for a number of special render effects that may be set on scene graph nodes to change the way they render.
This includes BillboardEffect, DecalEffect, etc.
RenderEffect represents render properties that must be applied as soon as they are encountered in the scene graph, rather than propagating down to the leaves. This is different from RenderAttrib, which represents properties like color and texture that don't do anything until they propagate down to a GeomNode.
You should not attempt to create or modify a RenderEffect directly; instead, use the make() method of the appropriate kind of effect you want. This will allocate and return a new RenderEffect of the appropriate type, and it may share pointers if possible. Do not modify the new RenderEffect if you wish to change its properties; instead, create a new one.

The destructor is responsible for removing the RenderEffect from the global set if it is there.

static |
Called immediately after complete_pointers(), this gives the object a chance to adjust its own pointer if desired.
Most objects don't change pointers after completion, but some need to.
Once this function has been called, the old pointer will no longer be accessed.

inline |
Provides an arbitrary ordering among all unique RenderEffects, so we can store the essentially different ones in a big set and throw away the rest.
This method is not needed outside of the RenderEffect class because all equivalent RenderEffect objects are guaranteed to share the same pointer; thus, a pointer comparison is always sufficient.

Lists all of the RenderEffects in the cache to the output stream, one per line.
This can be quite a lot of output if the cache is large, so be prepared.

Ensures that the cache is still stored in sorted order.
Returns true if so, false if there is a problem (which implies someone has modified one of the supposedly-const RenderEffect objects).
