and RNA for it independent of the build flag for enabling Freestyle. Suggested
by Sergey Sharybin through a code review of the branch.
* Many #ifdef WITH_FREESTYLE blocks were removed to always have Freestyle-specific
DNA file specification and RNA for it built in Blender. This will allow Freestyle
setting survive even when a non-Freestyle build is used for loading and saving
files. It is noted that operations are still conditionally built through #ifdef
WITH_FREESTYLE blocks.
* To this end, new blenkernel files BKE_freestyle.h and intern/freestyle.c have
been added. All API functions in FRS_freestyle_config.h as well as some of those
in FRS_freestyle.h were moved to the new files. Now the relocated API functions
have BKE_ prefix instead of FRS_.
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.

Resolved conflicts:
release/datafiles/startup.blend
source/blender/editors/space_nla/nla_buttons.c
Also updated source/blender/blenkernel/intern/linestyle.c as a follow-up of
recent changes for the use of bool.
Issue was caused by couple of circumstances:
- Normal Map node requires tesselated faces to compute tangent space
- All temporary meshes needed for Cycles export were adding to G.main
- Undo pushes would temporary set meshes tessfaces to NULL
- Moving node will cause undo push and tree re-evaluate fr preview
All this leads to threading conflict between preview render and undo
system.
Solved it in way that all temporary meshes are adding to that exact
Main which was passed to Cycles via BlendData. This required couple
of mechanic changes like adding extra parameter to *_add() functions
and adding some *_ex() functions to make it possible RNA adds objects
to Main passed to new() RNA function.
This was tricky to pass Main to RNA function and IMO that's not so
nice to pass main to function, so ended up with such decision:
- Object.to_mesh() will add temp mesh to G.main
- Added Main.meshes.new_from_object() which does the same as to_mesh,
but adds temporary mesh to specified Main.
So now all temporary meshes needed for preview render would be added
to preview_main which does not conflict with undo pushes.
Viewport render shall not be an issue because object sync happens from
main thread in this case.
It could be some issues with final render, but that's not so much
likely to happen, so shall be fine.
Thanks to Brecht for review!
Problem is that preview render database is being used, but the new datablock
function still uses G.main, and the mesh was being added to one database but
(attempted to be) removed from another. The proper fix would get rid of the
globals here, will look into that later.
New Outliner mode: "Main Data".
This shows a flattened, non-hierarchical list of all linkable "ID" data in
your current project. It works fine on searches. Actually this is the
view on the "Main" database in Blender, the one that's saved in a .blend.
This is in general more useful than the "Datablocks" viewer,
which is not searchable, and shows every property of data as well.
* Split and moved Cycles’ render layers panels into the render_layer
context as well (would be nice to hide this context when not needed,
e.g. with the BGE, but this is not so easy to do nicely...).
* Fixed some inconsistencies with trunk (probably due to svn merge
glitches) using r52858 as reference. Also recovered the missing
release/bin/blender-softwaregl file.
* A bunch of style code fixes in Blender's own code (not Freestyle
itself yet): line lengths, spaces around operators, block formatting,
headers, etc. In rna_linestyle.c, color_blend_items was replaced by
ramp_blend_items (exported from rna_material.c).

This commit also includes a fix of a bug identified during the merge and committed in revision 51853.
Thanks Thomas (dingto) for the timely fix!
Removing data then accessing would allow invalid memory access and often crash.
Example:
import bpy
image = bpy.data.images.new(name="a", width=5, height=5)
bpy.data.images.remove(image)
print(image.name)
Now access to the removed data raises an error:
ReferenceError: StructRNA of type Image has been removed
This is the same level of error checking that was done in blender 2.4x but was made difficult by RNA functions not having access to the PyObject's.
Added support of such features, as:
- Ability to call RNA functions using C++ classes
For example RenderEngine.tag_update
- Property setters (for scalars and arrays)
Used Qt/jQuery-like getters/setters style, meaning Class.prop() is a getter,
Class.prop(value) is a setter.
Still to come:
Collection functions are not currently registering inside a property
Meaning BlendData.meshes wouldn't be a subclass of BlendDataMeshes result
you'll need to explicitly create BlendDataMeshes for now instead of doing
BlendData.meshes.remove()
* new/remove for GPencil frames/strokes/
* add/pop for points
* clear for frame/layer & grease_pencil
* copy for frame
+ fix for free_gpencil_frames() not clearing the active frame

Also addressed code inconsistency due to changes in the trunk revision 50628 (color
management with OCIO) and 50806 (UV project material). OCIO-related changes are marked
OCIO_TODO as in some other files modified in revision 50628.
- freeing a mask from RNA BKE_libblock_free() twice on the mask.
- loading a new blend file would only free the mask and not unlink it from nodes - it would access freed memory.
