This separate probe rendering from viewport rendering, making possible to
run the baking in another thread (non blocking and faster).
The baked lighting is saved in the blend file. Nothing needs to be
recomputed on load.
There is a few missing bits / bugs:
- Cache cannot be saved to disk as a separate file, it is saved in the DNA
for now making file larger and memory usage higher.
- Auto update only cubemaps does update the grids (bug).
- Probes cannot be updated individually (considered as dynamic).
- Light Cache cannot be (re)generated during render.
Internal change needed for template support.
Loading the user preferences first so it's possible
for preferences to control startup behavior.
In general it's useful to load preferences before data-files,
so we know security settings for eg.

User Commit Log
---------------
* New Layer and Collection system to replace render layers and viewport layers.
* A layer is a set of collections of objects (and their drawing options) required for specific tasks.
* A collection is a set of objects, equivalent of the old layers in Blender. A collection can be shared across multiple layers.
* All Scenes have a master collection that all other collections are children of.
* New collection "context" tab (in Properties Editor)
* New temporary viewport "collections" panel to control per-collection
visibility
Missing User Features
---------------------
* Collection "Filter"
Option to add objects based on their names
* Collection Manager operators
The existing buttons are placeholders
* Collection Manager drawing
The editor main region is empty
* Collection Override
* Per-Collection engine settings
This will come as a separate commit, as part of the clay-engine branch
Dev Commit Log
--------------
* New DNA file (DNA_layer_types.h) with the new structs
We are replacing Base by a new extended Base while keeping it backward
compatible with some legacy settings (i.e., lay, flag_legacy).
Renamed all Base to BaseLegacy to make it clear the areas of code that
still need to be converted
Note: manual changes were required on - deg_builder_nodes.h, rna_object.c, KX_Light.cpp
* Unittesting for main syncronization requirements
- read, write, add/copy/remove objects, copy scene, collection
link/unlinking, context)
* New Editor: Collection Manager
Based on patch by Julian Eisel
This is extracted from the layer-manager branch. With the following changes:
- Renamed references of layer manager to collections manager
- I doesn't include the editors/space_collections/ draw and util files
- The drawing code itself will be implemented separately by Julian
* Base / Object:
A little note about them. Original Blender code would try to keep them
in sync through the code, juggling flags back and forth. This will now
be handled by Depsgraph, keeping Object and Bases more separated
throughout the non-rendering code.
Scene.base is being cleared in doversion, and the old viewport drawing
code was poorly converted to use the new bases while the new viewport
code doesn't get merged and replace the old one.
Python API Changes

```
- scene.layers

This is much more flexible solution which will allow doing some
more procedural features.

Root of the issue is that we do not re-read lib data blocks and ID placholders (ID_ID bheads)
in undo context (in `blo_read_file_internal`), because `BLO_read_from_memfile` copies
lib datablocks and Main data directly from oldmain.
The idea being, linked data do not change from undo/redo.
This is valid as long as linked data was not changed by the undo step - but if some
was deleted or localized, it will be missing from oldmain, leading to data loss
(note that does not only concern objects, all linkable data types can be affected,
at least in theory).
This commit addresses that issue by carefully mixing reuse of needed data from oldmain,
and "normal" re-reading of missing one. Makes us swimming in some rather dark waters,
and gives a rather non-easy-to-follow code, but it seems to work quite well,
and only other solution would be to get rid of that optimization
(not re-reading all libs on undo/redo), which is not acceptable.
Also, thanks to @carlosdp for initial investigation of the issue.

This patch avoids looping over bhead's linked list when looking up values by name.
Used during appaned and library loading.
Gives noticeable overall speedup loading files that used libraries. (nearly 2x on some Mango files)
This patch includes the work done in the terrible consequencer branch
that hasn't been merged to master minus a few controversial and WIP
stuff, like strip parenting, new sequence data structs and cuddly
widgets.
What is included:
* Strip extensions only when slipping. It can very easily be made an
option but with a few strips with overlapping durations it makes view
too crowded and difficult to make out.
* Threaded waveform loading + code that restores waveforms on undo (not
used though, since sound_load recreates everything. There's a patch for
review D876)
* Toggle to enable backdrop in the strip sequence editor
* Toggle to easily turn on/off waveform display
* Snapping during transform on sequence boundaries. Snapping to start or
end of selection depends on position of mouse when invoking the operator
* Snapping of timeline indicator in sequencer to strip boundaries. To
use just press and hold ctrl while dragging.

Summary:
Makes readfile.c more clear and easier to navigate in.
We would need to do such a move when we'll do 2.70 bump
anyway. So better be prepared.
In fact, as soon 2.70 bumo is done i would think we'd
better create versioning_270 file and do version code
there. Otherwise readfile.c will grow up dramatically
again.

PyNodes opens up the node system in Blender to scripters and adds a number of UI-level improvements.
=== Dynamic node type registration ===
Node types can now be added at runtime, using the RNA registration mechanism from python. This enables addons such as render engines to create a complete user interface with nodes.
Examples of how such nodes can be defined can be found in my personal wiki docs atm [1] and as a script template in release/scripts/templates_py/custom_nodes.py [2].
=== Node group improvements ===
Each node editor now has a tree history of edited node groups, which allows opening and editing nested node groups. The node editor also supports pinning now, so that different spaces can be used to edit different node groups simultaneously. For more ramblings and rationale see (really old) blog post on code.blender.org [3].
The interface of node groups has been overhauled. Sockets of a node group are no longer displayed in columns on either side, but instead special input/output nodes are used to mirror group sockets inside a node tree. This solves the problem of long node lines in groups and allows more adaptable node layout. Internal sockets can be exposed from a group by either connecting to the extension sockets in input/output nodes (shown as empty circle) or by adding sockets from the node property bar in the "Interface" panel. Further details such as the socket name can also be changed there.

- Packing .blend files
If you work a lot with dynamic linked .blend files ("Libraries"), it's always hard to
share your work with others (or for bug reports!).
This new option packs all used external .blend files, and - on save - combines it together
in one .blend file. You can save that file on any location.
Loading a packed .blend file then loads all library data usual - not editable.
Just use unpack to save out all linked .blend files. This will only save out the files
according the directory structure as was used on linking - relative to the current .blend.
It will create new directories, so be careful with unpacking when relative paths go up.
This feature also works fine for linked compressed .blend files.
It also works for many levels deep linked .blend hierarchies.
Access is hidden for now - I need to get some people to give it serious testing first.
You can find the options via spacebar search (try pack or unpack).
- Packed data and Undo
Now all packed data is excluded from the Undo buffer storage. Keeps undo memory smaller
and makes faster redo possible.

Commiting camera tracking integration gsoc project into trunk.
This commit includes:
- Bundled version of libmv library (with some changes against official repo,
re-sync with libmv repo a bit later)
- New datatype ID called MovieClip which is optimized to work with movie
clips (both of movie files and image sequences) and doing camera/motion
tracking operations.
- New editor called Clip Editor which is currently used for motion/tracking
stuff only, but which can be easily extended to work with masks too.
This editor supports:
* Loading movie files/image sequences
* Build proxies with different size for loaded movie clip, also supports
building undistorted proxies to increase speed of playback in
undistorted mode.
* Manual lens distortion mode calibration using grid and grease pencil
* Supervised 2D tracking using two different algorithms KLT and SAD.
* Basic algorithm for feature detection
* Camera motion solving. scene orientation
- New constraints to "link" scene objects with solved motions from clip:
* Follow Track (make object follow 2D motion of track with given name
or parent object to reconstructed 3D position of track)
* Camera Solver to make camera moving in the same way as reconstructed camera
This commit NOT includes changes from tomato branch:
- New nodes (they'll be commited as separated patch)
- Automatic image offset guessing for image input node and image editor
(need to do more tests and gather more feedback)
- Code cleanup in libmv-capi. It's not so critical cleanup, just increasing
readability and understanadability of code. Better to make this chaneg when
Keir will finish his current patch.
More details about this project can be found on this page:
http://wiki.blender.org/index.php/User:Nazg-gul/GSoC-2011
Further development of small features would be done in trunk, bigger/experimental
features would first be implemented in tomato branch.
- rename 'name', 'dir' --> 'filepath' where these actually represent a file path to avoid confusion.
- bugfix for possible (but unlikely) uninitialized string.
- remove commented script append function, now we have a python api for this.
Also use const char in many other parts of blenders code.
Currently this gives warnings for setting operator id, label and description since these are an exception and allocated beforehand.
- made interface, windowmanager, readfile build without unused warnings.
- re-arranged CMake's source/blender build order so less changed libs are build later, eg: IK, avi
* sound file path was not displayed in sequencer panel.
* sound strip with relative paths would stop working after undo.
(commit 27575 by Brecht from render25 branch)
that completely:
* quit.blend is saved from the undo file, which did not save out library
ID_LI and ID_ID blocks, for quick undo keeping the library datablocks.
However this means library links are lost on reading the quit.blend, so
now instead of not writing them, they are not read on undo.
* Libraries were not not using the right path yet always.
Note the screen setup is still not recovered from the quit.blend if no
auto save happened yet, but that is not important enough to spend time on
now.
* Added Shading and Performance panels in the scene buttons,
containing the options previously in the 2.4x game menu.
* Added show framerate/debug/physics/warnings back in game menu.
* Moved these settings from G.fileflags to scene GameData.
* Enabled Display Lists by default.
* Some other small game scene button tweaks.
From the anti-globalization department:
G.obedit terminated!
Wherever possible, use CTX_data_edit_object(C) to get this
now. It's stored in scene now, and the screen context has
it defined.
* Added a report list to operator, to which they can report errors and
warnings. When the operator ends, it will display them with a popup. For
python these should become exceptions when calling operators.
* Added a function to make a popup menu from a report list.
* Also added a utility function to prepend a string before the reports to
indicate what they relates to. Also made the report functions used
BLI_dynstr to simplify the code.
* Made file reading and writing report errors to the user again using this
system, also replacing the left over uncommented bad level error() calls.
- removed context usage, should not be in this module
- remove G.main usage, now is passed along
- still some globals in use here, goal is to get rid of those too,
so that it's possible to load/save blendfiles without having to
think about some global state.
* When making a proxy, the lib linked IPO driver was also changed to
point to the proxy object, and after undo this local proxy object
was replaced so the pointer became invalid. In fact it is not needed
at all to change this because the IPO code maps the pointer to the
local proxy object already.
* Undoing the make proxy operation would crash because the proxy_from
pointer in the library linked object would still point to the removed
object. Now it clears all these pointers before undo, because on each
undo memory file read they will be set again anyway.
