1) Cone and cylinder uv_mapping have been added to the 3.7.1 master
branch compliments of Jérôme. We'll need to update the supported objects
at:
http://wiki.povray.org/content/Reference:UV_Mapping
to reflect this. I believe the behavior is essentially like that of the
recently add lemon uv_mapping - but Jérôme knows best.
2) We've decided to leave the uv_mapping of the torus reversed in U
relative to other uv_mapping given it has been this way for a long time
(early 2000s I think).
I think adding a note its mapping is reversed in U with respect to
others would be good.

started a new section:
http://wiki.povray.org/content/Reference_Talk:UV_Mapping#Supported_Objects_Updates
i'll keep an eye on that then do the updates later

Additions look good to me Jim - thanks.

Does this mean the map_type 3 and 4 are in development,
for POV-Ray, to add more basic mappings to any object even meshes and
environment textures, like:
FLAT map_type 0
SPHERE map_type 1
TUBE map_type 2?
CYLINDER?
CONE?
any CUBE? or still have to use "warp { cubic }..."

Judging from your question, I presume you're not familiar with POV-Ray's
`uv_mapping` keyword.
You can think of this as a "default warp" that is different for each
primitive.
(A drawback of `uv_mapping`, is that it is only useful for surface
textures, whereas `warp` can also be used for volumetric effects.)
