The projection code was already in place, so this just exposes the option.

Combine all the highpoly pixel arrays into a single array with a lookup
object_id for each of the highpoly objects.
Note: This changes the Bake API, external engines should refer to the
bake_api.c for the latest API.
Many thanks for Sergey Sharybin for the complete review, changes
suggestion and feedback. (you rock!)

There were some synchronization missing in cases when only one of those settings
was disabled.
Also added a render test for such configurations now.

Did some bad spacing in recent commits, better to get rid of those so
they does not confuse those who're working on sources.

There were two major problems with the interactivity of material previews:
- Beckmann tables were re-generated on every material tweak.
This is because preview scene is not set to be persistent, so re-triggering
the render leads to the full scene re-sync.
- Images could take rather noticeable time to load with OIIO from the disk
on every tweak.
This patch addressed this two issues in the following way:
- Beckmann tables are now static on CPU memory.
They're couple of hundred kilobytes only, so wouldn't expect this to be
an issue. And they're needed for almost every render anyway.
This actually also makes blackbody table to be static, but it's even smaller
than beckmann table.
Not totally happy with this approach, but others seems to complicate things
quite a bit with all this render engine life time and so..
- For preview rendering all images are considered to be built-in. This means
instead of OIIO which re-loads images on every re-render they're coming
from ImBuf cache which is fully manageable from blender side and unused
images gets freed later.
This would make it impossible to have mipmapping with OSL for now, but we'll
be working on that later anyway and don't think mipmaps are really so crucial
for the material preview.
This seems to be a better alternative to making preview scene persistent,
because of much optimal memory control from blender side.

Missing Bits
============
First rule of Multi-View bug report: If something is not working as it should *when Views is off* this is a severe bug, do mention this in the report.
Second rule is, if something works *when Views is off* but doesn't (or crashes) when *Views is on*, this is a important bug. Do mention this in the report.
Everything else is likely small todos, and may wait until we are sure none of the above is happening.
Apart from that there are those known issues:
* Compositor Image Node poorly working for Multi-View OpenEXR
(this was working prefectly before the 'Use Multi-View' functionality)
* Selecting camera from Multi-View when looking from camera is problematic
* Animation Playback (ctrl+F11) doesn't support stereo formats
* Wrong filepath when trying to play back animated scene
* Viewport Rendering doesn't support Multi-View
* Overscan Rendering
* Fullscreen display modes need to warn the user
* Object copy should be aware of views suffix

It is still possible to free a bit more memory by detecting buildin images
which are not used by shaders, but that's not going to improve memory usage
that much to bother about this now.
Such change brings peak memory usage from 4.1GB to 3.4GB when rendering
01_01_01_D layout scene from the Gooseberry project. Mainly because of
freeing memory used by rather huge environment map in the viewport.

This inconsistency drove me totally crazy, it's really confusing
when it's inconsistent especially when you work on both Cycles and
Blender sides.
Shouldn;t cause merge PITA, it's whitespace changes only, Git should
be able to merge it nicely.

Issue was caused by cycles in shader graph confusing it's
simplification stage. Now we're ignoring links which are
marked as invalid from blender side so we don't run into
such cycles and keep graph code simple.

A new checkbox "High quality" is provided in camera settings to enable
this. This creates a depth of field that is much closer to the rendered
result and even supports aperture blades in the effect, but it's more
expensive too. There are optimizations to do here since the technique is
very fill rate heavy.
People, be careful, this -can- lock up your screen if depth of field
blurring is too extreme.
Technical details:
This uses geometry shaders + instancing and is an adaptation of
techniques gathered from

http://advances.realtimerendering.com/s2011/SousaSchulzKazyan%20-
%20in%20Real-Time%20Rendering%20Course).ppt
TODOs:
* Support dithering to minimize banding.
* Optimize fill rate in geometry shader.

The purpose of this change is to add extra possibility to render engines and
export scripts to reduce peak memory footprint during their operation.
This new argument should be used with care since it'll leave mesh in not really
compatible with blender format, but it's ok to be used on temp meshes.
Unfortunately, it's hard to get scene where it'll show huge benefit because
in my tests with cycles peak memory is reached in MEM_printmemlist_stats().
However, in the file with sintel dragon it gives around 1gig of memory benefit
after removing the polys which would allow other heavy to compute stuff such as
hair (or even pointiness calculation) to not be a peak memory usage.
In any case, this change is nice to have IMO, and only means more parts of
scene export code should be optimized memory-wise.

Issue this commit is addressed to is that particle system and particle modifier
will contain caches once derived mesh was requested and this cached data will
never be freed.
This could easily lead to unwanted memory peaks during synchronization stage
of rendering.
The idea is to have RNA function in object which would free caches which can't
be freed otherwise. This function is not intended to deal with derived final
since it might be used by other objects (for example by object with boolean
modifier).
This cache freeing is only happening in the background rendering and locked
interface rendering.
From quick tests with victor file this change reduces peak memory usage by
command line rendering by around 6% (1780MB vs. 1883MB). For rendering from
the interface it's about 12% (1763MB vs. 1998MB).

Was missing do-versions code after rotation order change in Cycles.
This is a regression and to be ported to the final release branch.
|

Reporting mesh name is not really useful, since it's name does not
any relation with the original object/mesh names.
|

Currently should be no functional changes, but nice thing to have fixed
for some further experiments.
|
|
This ways previews are refreshing with the same ratio as job was expecting
this to happen, giving more instant feedback on the changes.
|
|
This is a bit more logical, as it better represents the 3 primitive types we have.
|
|
OpenCL doesn't let you to get address of vector components, which
is kinda annoying. On the other hand, maybe now compiler will have
more chances to optimize something out.
|

This flag is global for all the sessions and never changes. so it doesn't
really make sense to pass it around to all sessions and synchronization
routines.
Switched to a static member of BlenderSession now, but it's probably more
logical to introduce some sort of BlenderGlobals. Doesn't currently worth
a hassle for a single boolean flag tho.
|
|
This way we can do some more aggressive policy about releasing temporary
data during synchronization.

Simple fix: all vertex attributes should be filled in before split.

set as focused
|
|
In the worst case it'll do nothing, in the best case it might give some percent
of speedup because of better cache coherency.
Currently it's all handled as an override on blender_python level, don't really
see reason to penetrate the boolean flag further into sync code. This can always
be done later if needed.

This makes overall code of create_mesh() much cleaner and easier to follow.

This attribute means how "pointy" the geometry surface is, which allows to do
effects like dirt maps and wear-off effects on render geometry. This means the
attribute is calculated for the final mesh which means no baking (which implies
UV unwrap) is needed. Apart from this the behavior is quite close to how vertex
dirty colors works.
The new attribute is available as an output socket of Geometry node.
There's no penalty for the render time, only some delay on scene preparation
(the delay is linear of the mesh complexity).

This is the core code for it, tools (datatransfer and modifier) will come in next commits).
RNA api is already there, though.
See the code for details, but basically, we define, for each 'smooth fan'
(which is a set of adjacent loops around a same vertex that are smooth, i.e. have a single same normal),
a 'loop normal space' (or lnor space), using auto-computed normal and relevant edges, and store
custom normal as two angular factors inside that space. This allows to have custom normals
'following' deformations of the geometry, and to only save two shorts per loop in new clnor CDLayer.
Normal manipulation (editing, mixing, interpolating, etc.) shall always happen with plain 3D vectors normals,
and be converted back into storage format at the end.
Clnor computation has also been threaded (at least for Mesh case, not for BMesh), since the process can
be rather heavy with high poly meshes.
Also, bumping subversion, and fix mess in 2.70 versioning code.

also remove empty class parenthesis

The issue was caused by the whole viewplane used for mapping calculation
which would for sure lead to differences between final camera render and
viewport render from the camera view.
This commit makes it so window texture mapping is the same as final render
when viewing from the camera in viewport render.
It's not totally clear what's the right thing to do when viewport is not
in the camera view mode and that part is left unchanged.

This is the same as blender internal's texture mapping from another object,
so this way it's possible to control texture space of one object by another.
Quite straightforward change apart from the workaround for the stupidness of
the dependency graph. Now shader has flag telling that it depends on object
transform. This is the simplest way to know which shaders needs to be tagged
for update when object changes. This might give some false-positive tags now
but reducing them should not be priority for Cycles and rather be a priority
to bring new dependency graph.
Also GLSL preview does not support using other object for mapping.
This is actually correct for BI shading as well and to be addressed as
a part of general GLSL viewport improvements since it's not really clear
how to support this in GLSL.

Root of the issue goes to the fact that since the very beginning Cycles was
using ZYX euler rotation for mapping shader node but blender was always
using XYZ euler rotation.
This commit switches Cycles to use XYZ euler order and adds versioning code
to preserve backward compatibility.
There was no really nice solution here because either we're ending up with
versioning code or we'll need to deal with all sort of exceptions from blender
side in order to support ZYX order for the mapping node. The latest one is
also creepy from the other render engines points of view -- that might break
compatibility with existing bindings or introduce some extra headache for them
in the future.
This could also become a PITA for us with need of supporting all sort of weird
and wonderful exceptions in the refactored viewport project.
NOTE: This commit breaks forward compatibility, meaning opening new files in
older blender might not give proper result if Mapping node was used.
Also, libraries are to be re-saved separately from the scene file, otherwise
versioning code for them wouldn't run if scene file was re-saved with new
version of blender.

Issue was, when requesting (building) lnors for a mesh that has
autosmooth disabled, one would expect to simply get vnors as lnors.
Until now, it wasn't the case, which was bad e.g. for normal projections
of loops in recent remap code (projecting along split loop normals
when you would expect projection along vertex normals...).
Also, removed the 'angle' parameter from RNA's `mesh.calc_normals_split`.
This should *always* use mesh settings (both autosmooth and smoothresh),
otherwise once again we'd get inconsistencies in some cases.
Will update fbx and obj addons too.
