I ran across the following in the v1.0 source code the other day while 
trying to understand the history of something:

/* Image/Bump Map projection methods */
#define PLANAR_MAP      0
#define SPHERICAL_MAP   1
#define PARABOLIC_MAP   3
#define TORUS_MAP       5
#define PIRIFORM_MAP    6
#define OLD_MAP         7

I guess v3.8's type 7 (angular light probe?) took OLD_MAP's slot :-).

The documentation has forever said types 3 & 4 are under development, 
but I've never spotted any actual code indicating this ever true beyond 
an intent. FWIW.
