Bugfix #3514

Once an Object Ipo position was inserted, the object couldn't be moved when
a particle system was tied to it. Needed code to copy object settings,
before the particle animation was done.

Bugfix #3512

Duplicated objects, that have modifiers, didn't render (or not correct).
Bug reported case with softbody being duplicated.

The duplicator system is ancient... integration with new derivedmesh or
modifiers has not been really done yet.

Hrms... setting the undosteps to zero then should also work! :)

Bugfix #3507

Global Undo didn't use the 'undo steps' value in the user presets yet...
even whilst button mentioned 'editmode undo' there, an easy fix to add.

Fix unchecked parameter in M_Ipo_Recalc, and some documentation fixes.

-- remove unused variable "dict" which was giving compiler warnings.

fix for exotic msvc6 projects building
so i think i can do, though we're BCON-4 ( official builds are VC7 anyway )

building elbeem debug lib with proper threading model

Orange bramch:
New diffuse shader, "Fresnel", which using existing fresnel formula.
Since it hilights edges (away from lamp), nice to fill darker parts with
the new layering system.

Weird stuff though;

(Movie disappears in a couple of days!)

Note; for ray-shadow you need to use the Bias, to prevent 'terminator'
problems. I made that option default now.

-- Fix segfault when callign Blender.Armature.Get() with no parameters

Dang, another fix in orange tree... I keep spamming commit maillist that
way!

This fixes a sometimes-crash when doing previews for world or lamp.

Orange: two fixes,

- Texture buttons preview didn't show for material layers
- layers now have a 'number of users' button, which allows to make a
full copy of the material.

Sunday sync of Orange with bf-blender

Bf-blender commit! :)

Forgot to put back window/screen-size clipping when opening render window.
Note for windows coders; check this diff, here's where you might need to
add an ifdef too for windows, to get the window opening correct for the
top of the screen (probably because of windows bottom toolbar?)

Orange 'layer commit' fix: Texture buttons crash when selecting an empty
texture channel

Orange fix: previous commit from Brecht called unwrap_lscm_live_end()
without check for correct spacetype in use. :)

Orange branch feature; Material Layering

(WIP, don't bugs for this in tracker yet please!)

- New Panel "Layers" in Material buttons, allows to add unlimited amount
of materials on top of each other.
- Every Layer is actually just another Material, which gets rendered/shaded
(including texture), and then added on top of previous layer with an
operation like Mix, Add, Mult, etc.
- Layers render fully independent, so bumpmaps are not passed on to next
layers.
- Per Layer you can set if it influences Diffuse, Specular or Alpha
- If a Material returns alpha (like from texture), the alpha value is
used for adding the layers too.
- New texture "Map To" channel allows to have a texture work on a Layer
- Each layer, including basis Material, can be turned on/off individually

Notes:

- at this moment, the full shading pass happens for each layer, including
shadow, AO and raytraced mirror or transparency...
- I had to remove old hacks from preview render, which corrected reflected
normals for preview texturing.
- still needs loadsa testing!

More work on the new unwrapper code (orange branch):

- There is now a (temporary) dropdown box in the image window header for
switching between the old an new unwrapper code. So to test the changes
described below you need to enable the new unwrapper code.
- Pinning is now more predictable, if one uv is pinned, the others belonging
to the same vertex are pinned also.
- Live LSCM is much faster, since the LU factorization, the most expensive
part of the computation, is now stored and reused (was Jens' idea).
- Packing multiple uv charts is slightly improved, by doing a binary search
over the texture width. This fixes the case where all the charts are
packed at the bottom of the image.
- LSCM now uses an angle based formulation, and the results seem somewhat
different (maybe slightly better?), didn't find out why yet.

- fixed output behaviour (now behaves just like render output,
thus directories in the path are created using RE_make_existing_file
in fluidsim.c)
- changed default output to be '//fluidsimdata/...'
- hopefully fixed bugs #3466 and #3470 (orco texture coords caused
problems when the fluidsim mesh was bigger than the original one,
one no other deformations were used - new deformedVerts are now
allocated in this case in DerivedMesh.c)

Added Copy/Paste 'mapping' options for World/Lamp buttons.

Also: moved render defines from scene to render module itself.

Orange tree:
Raytrace mirror crash, due to mixup in skyshade call (for 'glob' texture)
