make FUNCTIONs like so
    function {FORMULA (<parameters>) }
  map{[<1Dval>, <XDmapentry>][<2Dval>, <XDmapentry>][<XDval>,
<XDmapentry>]...}// this maps a function from a 1D var to a colour,
normal etc & others.
  FORMULA = ( ["dll-name"] func-name) | macro-name | formula
   if dll-name is not used pov functions are used
and revamp textures, normals, etc to be able to use these
eg I could use this to have a different pattern for each rgbft channel
by adding the values ...

allow the type of a variable to be obtainable eg gettype(myvar)

Drop "#declare" for non-new variables

"extendable objects, finishes, media, etc"
    #declare myobjtype = new object{ intersections FUNCTION,
surfacehandler FUNCTION, interiorhandler FUNCTION...}
so that you can make custom shaped objects, do freaky stuff to the ray
when it leaves a surface, do freaky stuff to the ray as it goes through
an interior

make POV an object oriented program so the above is possible
    #declare myobj = struct {...}

get the PolyRay author to add a tesselate object modifier

line lights - interpolate between the ends somehow??
with spline stuff
and go from there to triangle lights and then to object lights (maybe
using photons)

displacement  mapping, mapping of any and all texture parameters using
images

have the struct that determines syntax highlighting in the POV-Ray src
(instead of the CodeMax support code) so that
patches can use proper syntax highlighting for their new keywords etc.

  Povray is NOT a windows program.

So what's wrong with windows platform specific suggestions where the
codemax editor is concerned ? I mean like the Mac version has built
in Quicktime support for compiling animation the other platforms
don't have and you don't hear me bitching about that do you ? Well
not much anyway :)

  If I understood correctly, he suggested that it would be possible to
specify a "dll-name" in the pov-script. This makes no sense since the
povray script is not platform-dependant.
  It was also unclear how the struct for syntax highlighting would work and
where would it be located.

	It isn't?  I wonder what I installed on my Windows NT box

	That's silly.  The core should be kept portable,
	but people should be able to use current technology
	to get what they want out of POVray.

	It's possible to write platform independent code in 
	C++ - but it's not enforced.  The same philosophy should
	apply to POV.

	Things like POV-CSDL - grafting an interpreted C'ish
	kind of thing onto POV - goes to show the extreme
	measures we'd need to enforce the portablity of
	pov scenes, while still not giving people what they 
	really want - a true programmatic interface, in the
	language of their choice.

This, at least, should be available before 4.0, assuming all goes according
to plan and so on.  But note the disclaimer; this is not an official 
proclamation.

Well... it's possible in SuperPatch, which runs on platforms where DLLs
don't make sense.  But it won't be in 3.5, or in 4.0.

If we just used the patch I sent to Chris back just before I joined the 
POV-Team, it'd be built on the fly by the Windows support code and sent to 
the Codemax handler.  It's currently hard-coded in the Codemax support DLL.  
But we won't be using that patch, so that's not how it will work.

Don't worry, it's not intended to be cross-platform; this is a Windows-only 
thing, for a Windows-only editor. You may continue to use pov-mode.el syntax 
highlighting.

  Nope, povray is an ANSI-C program. It has been ported to several platforms,
like Windows, but that doesn't make it a Windows program. The binary you
installed is a windows compile of the program, but povray itself is not a
windows program.

  Nope, it's not silly. Many people are using povray in a wide variety of
platforms (which support or don't graphical user interfaces).

  No it shouldn't. Povray has to be able to compile in any platform which
has the proper compiler. Portability is a very serious issue.
  I understand why most windows users just can't understand how someone likes
to use something else than windows and graphical programs.

  Pov scenes and the povray source code are two completely different things.
Don't mix them.

	Yes it should.  Enforced portability is very limiting.
	I'm talking about the portability of POV scenes,
	not the C implementation - which I agree should be
	kept portable.

	I'm not, you are.

*boggle*  You're saying it would be good to be able to make POV scenes that 
don't render on every platform for a given version of POV?  Can we just send
all the support questions to you?  What color is the sky in your world?
