The Image texture repeat options, now allow a "Checker" repeat. With
odd and even tiles set separately, and a size button to set a
'Mortar' inbetween tiles.

Also fixed bug: using 'CalcAlpha' option for image textures didn't give
antialised edges for image.
Basically this provides three new things:
1. Choice of a list of noise-base functions, which can be used by the
current Clouds, Marble, Wood textures as well.
2. Three new texture types: Musgrave, Voronoi and DistortedNoise
3. Python access to noise functions (not for render!)
All of this together makes Blender's builtin procedural textures a LOT
more powerful. Here again, a full webpage should be made to show off all
possibilities, and explain some of the more scientific names for settings.
A good read on Musgrave textures can be found here:

I can't find official DistortedNoise docs easily... maybe its something
Eeshlo created himself.
I've spent some time to change the patch Eeshlo provided. Worth noting:
- created main texture "Musgrave" with 5 sub choices (instead of 5 new
main textures)
- added for all new textures the option to scale (zoom in out)
- added patch in do_versions to initialize variables
I hope the Python team will check on the Noise.c API. And include in docs!
different objects shouldn't share flags this way (still sharing of
other mesh flags in renderer... ickity pickity, but I'm not fixing now)
- removed some unnecessary uses of DNA_mesh_types.h
Main target was to make the inner rendering loop using no globals anymore.
This is essential for proper usage while raytracing, it caused a lot of
hacks in the raycode as well, which even didn't work correctly for all
situations (textures especially).
Done this by creating a new local struct RenderInput, which replaces usage
of the global struct Render R. The latter now only is used to denote
image size, viewmatrix, and the like.
Making the inner render loops using no globals caused 1000s of vars to
be changed... but the result definitely is much nicer code, which enables
making 'real' shaders in a next stage.
It also enabled me to remove the hacks from ray.c
Then i went to the task of removing redundant code. Especially the calculus
of texture coords took place (identical) in three locations.
Most obvious is the change in the unified render part, which is much less
code now; it uses the same rendering routines as normal render now.
(Note; not for halos yet!)
I also removed 6 files called 'shadowbuffer' something. This was experimen-
tal stuff from NaN days. And again saved a lot of double used code.
Finally I went over the blenkernel and blender/src calls to render stuff.
Here the same local data is used now, resulting in less dependency.
I also moved render-texture to the render module, this was still in Kernel.
(new file: texture.c)
So! After this commit I will check on the autofiles, to try to fix that.
MSVC people have to do it themselves.
This commit will need quite some testing help, but I'm around!
- added 'Mapping to" channel "RayMirror", to control mirror with texture
- fixed bug in using mirror-rgb as texture channel... this is cumbersome
because it is abused by Envmap in a not nice way. Fixing the abuse will
cause compatibility errors, which can be fixed when we up release # to
2.32.
- added "Translucency", which is nothing else than allowing another
shading pass for the backside of a face (with normal inverted). This
is interesting for all kinds of situations where you want light from
behind to 'shine through'. Also works to reduce dark areas in
unlighted parts of rendering transparent faces. Light from behind on
transparent red window should make it glowing some, right?!
- added texture channel for this as well
- Reorganized Material Panels to reveil some consistancy where buttons
can be found. Not perfect yet, but at least all options for Shaders and
options for Mirror & Transparency now are together.
This gives some space in Shader Panel for nice expansion.
instead of the old 'septex' which only showed the active one
- rendering: the 'stencil' option now works to stencil out normals as well
(special requests from our manual master, s68)
Multiple environments now can be rendered in one pass. Previously the other objects with environment maps didn't show up in a reflection. Like this:

By default, Blender renders now this result:
http://www.blender.org/bf/dep0.jpg
For a further 'recursive ray-tracing effect' you can give each EnvMap texture a higher "Depth" value. Here is a result with depth set at '2':

Related new options:
- in (F10) DisplayButtons, environment map rendering can be turned on and off.
- in EnvMap texture buttons you can free all environment maps
- Environment map sizes are also reduced with the (F10) 'percentage' option.
Tech note: with this commit the VlakRen struct has on *ob pointer!
