|
** can keep track of the object it is supposed to be projecting and refresh
|
|
** its texture only when needed. In addition, it stores the 'ID' of the
|
|
** light source which generated it so that we can re-use the same DynTexProjectClass's
|
|
** when the same object is being projected by the same light source (see the
|
|
** Update_Texture call in MovePhysClass...)
|
|
** NOTE: the pointer back to the projected object is not ref-counted because
|
|
** that would create a circular reference.
