- Add paste from system clipboard which behaves like paste from file.
- Paste from file now replaces the selection rather then just adding to the end.
- Move paste operations into the 'Edit' menu.
- Added generic paste functions: font_paste_wchar, font_paste_utf8.
- Fix paste max length check not taking the selection length into account.

Issue was caused by BKE_vfont_to_curve() modifying curve->nurbs list which
gave threading issues.
Now added BKE_vfont_to_curve_nubase() which operates on a given nurbs list
base which is local in do_makeDispListCurveTypes().
By the looks of it it wouldn't give speed regression because previously it
also was creating nurbs for every font object sharing the same curve data.

Main issue here is that glBuf* calls were invoked from threads different than
main thread. This caused a crash (since those do not have a GL context active).
Fix here is twofold:
* add an ID buffer in buffer pool that handles pbvh buffers and is freed
from main thread when gpu_buffer_pool_free_unused is called.
* do not create glbuffers in derivedmesh creation routine, rather tag nodes
for update and create those in the draw function
(guaranteed to be called from main thread)

Avoids having small values displayed as "0kg".

Convert int to bool.

Issue seems to be caused by thread-unsafe IMB_freeImBuf.
Now use generic BKE_image_release_ibuf to de-reference
image buffer which was acquired from image datablock.

reflect that. Previous name GPU_Buffers was very similar to GPU_Buffer,
renamed to GPU_PBVH_Buffers

EditFont's use of Curve.len was very confusing, in editmode it
represented the number of characters, in object mode the number of
bytes. add Curve.len_wchar and keep track of both.
Also don't convert the editmode text into utf8 on every keystroke.
Now this is done on exiting editmode or save - to match most other
object types.
This also fixes curves 'body_format' being reported with an invalid size.

Summary:
Crash was happening because of fcurve modifier stack
used modifier's DNA to store temporary data.
Now made it so storage for such a thing is being
allocated locally per object update so multiple objects
which shares the same animation wouldn't run into
threading conflict anymore.
This storage might be a part of EvaluationContext,
but that'd mean passing this context all over in
object_where_is which will clutter API for now without
actual benefit for this.
Optimization notes: storage is only being allocated
if there're Cycles modifier in the stack, so there're
no extra allocations happening in all other cases.
To make code a bit less cluttered with this storage
passing all over the place added extra callbacks to
the FModifier storage which runs evaluation with the
given storage.

File tracking.c became rather huge and annoying to
maintain and it really contains several independent
areas of motrack pipeline.
Now we've got:
* tracking.c: general-purpose functions which are used
by blender, clip editor, RNA and so.
* tracking_detect.c: feature detection functions
(blender-side, logic is still in libmv).
* tracking_plane_tracker.c: blender-side 2D tracking logic.
* tracking_plane_tracker.c: plane track tracker.
* tracking_solver.c: functions for camera solving.
* tracking_stabilize.c: 2D stabilization functions.
* tracking_util.c: utility functions for all those files
and which shouldn't be public.

Summary:
Issue was caused by the same tile being written twice to
the EXR file. This was happening because of partial update
of work-in-progress tiles was merging result to the final
render result in order to make color management pipeline
happy.
We need to avoid such a merges and keep memory usage as
low as possible when Save Buffers is enabled.
Now render pipeline will allocate special display buffer
in render layer which will contain combined pass in the
display space. This keeps memory usage as low as we can
do at this moment.
There's one weak thing which is changing color management
settings during rendering would lead to lossy conversion.
This is because render result's display buffer uses color
space from the time when rendering was invoked.
This is actually what was happening in previous release
already actually so not a big issue.

Solved by adding RW lock to BKE_vfont_to_curve.
So now all the threads are allowed to read chars from ghash,
but they'll be locked as soon as one thread would need to load
more chars from font to the ghash.

absorption.
This is the simplest possible volume rendering case, constant density inside
the volume and no scattering or emission. My plan is to tweak, verify and commit
more volume rendering effects one by one, doing it all at once makes it
difficult to verify correctness and track down bugs.
Documentation is here:
http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Materials/Volume
Currently this hooks into path tracing in 3 ways, which should get us pretty
far until we add more advanced light sampling. These 3 hooks are repeated in
the path tracing, branched path tracing and transparent shadow code:
* Determine active volume shader at start of the path
* Change active volume shader on transmission through a surface
* Light attenuation over line segments between camera, surfaces and background
This is work by "storm", Stuart Broadfoot, Thomas Dinges and myself.

* Henyey-Greenstein scattering closure implementation.
* Rename transparent to absorption node and isotropic to scatter node.
* Volume density is folded into the closure weights.
* OSL support for volume closures and nodes.
* This commit has no user visible changes, there is no volume render code yet.
This is work by "storm", Stuart Broadfoot, Thomas Dinges and myself.

tree ID data when freeing bNodeTree data blocks, while also making sure
localized node group copies get freed properly.

also remove redundant call to wcslen and ensure FT_Init_FreeType runs
once the font loads.

Remove unneeded nested if statements.
Avoid mixing short and bool.

Issue was caused by missing objects update for temporary
freestyle objects. This happened because of the fact that
such objects doesn't have any relations, as in they're
corresponding to root nodes in the DAG.
This situation wasn't handled by DAG_threaded_update_begin()
which considered there's only one root node in the DAG.
