TRenderAlpha

Comment:

This class is used to render the alpha (transparent) objects. As an alpha object is found, a TRenderAlpha object is created that includes:
	- the object
	- its parent frame (if needed - probably not)
	- its current world transform, which is used to transform the object into world coordinates.
	- the distance from the camera. This is used to sort the alpha objects when it is rendered later.
