Actually two errors here:
* Properties editor wasn't refreshing on (NC_SCENE | ND_RENDER_OPTIONS) notifiers
* Was using notifier info bits wrongly, needs to send two separate notifiers
Decided to remove ND_RENDER_OPTIONS rather than adding properties editor scene context refresh for it, this is more than a render option change.
Duplicates can happen at UV seams in case of resolution mismatch
or other complications. It's better not to store them in case it
confuses some math later on.

1. When adding one pixel border to UV islands prefer grid directions.
This is more logical as it means neighbor pixels will commonly
share a border, opposed to just corners.
2. Don't subtract 0.5 when converting float UVs to int in computing
adjacency across a UV seam. Pixels cover a square with corners
at int positions and adding/subtracting 0.5 is only for dealing
with the center point of a pixel.
3. Use the neighbour_pixel field from the correct pixel, and check
it's not back to the origin point.
4. In the connected UV case, ensure that the returned index actually
refers to a valid active pixel.
This fixes paint spread not traversing some UV seams, while at the
same time spreading to random unrelated points on other seams.
The first problem is primarily fixed by 2, while the second one
is addressed by item 4.

Moved that code forth and back a few times while creating rB776a8548f03a fix,
ended up forgetting to update it correctly for function where it layed down in the end.
Last-minute fixes are never a good thing... Now we already have real reason for 2.78 'a' release :(
Regression from rBa4a968f, we would adjust current point's wetness without actually protecting it
in new multi-threaded context, leading to concurrent access mess.
Now delay applying wetness reduction to current point to end of function, allows us to avoid having
to lock current point twice together with neighbor one (and reducing spinlock awainting too).
To be backported to 2.78a.
Never call function that might recompute a DM in an RNA itemf callback (or any UI-related func in general)!
There was an XXX comment asking if this was OK - well, no, it was not. :P
Could be ported back to some 2.78 flavour should we need it.
WARNING! Full build is broken, alembic has not been merged in correctly and has some references to particle stuff.
Don't have time to tackle this now (and probably would be better if someone knowing what he's doing does it anyway).

Was only happening with new dependency graph.
The issue here is that scene's depsgraph layers will be 0 unless
it was ever visible. Worked around by checking for 0 layer in the
update_tagged of new depsgraph. This currently kind of following
logic of visible_layers, but is weak.
Committing so studio is unlocked here, will re-evaluate this layer.
Now using new system dedicated to that kind of cases, id_ensure_real_user(), instead.
That way, usercount of Scenes is handled correctly at deletion time.
Reported by @sergey over IRC, thanks.
Complete (for our needs) 2D & 3D transformation API. Should be easy to port legacy OpenGL matrix stack-based code to this. Still needs testing.
Ported ortho, frustum, lookAt functions from Viewport FX (rB194998766c65). Kept plenty of Viewport FX code from previous commit.
Stack API and 2D routines ported from Gawain. This version uses BLI_math library so everything is licensed under GPL instead of the usual MPL.

- WITH_SMOKE macro was not defined so some code was not compiled, though
it was still accessible from the UI
- some UI elements were disappearing due to bad indentation, also rework
the UI code to not hide but rather disable/grey out button in the UI
- Display thickness was not used due to bad manual merge of the code
from the patch.
mul_m4_m4m4(R, A, B) gives us R = AB in general. Existing code assumed the worst, that A and B both alias the output R. For safety it makes internal copies of A and B before calculating & writing R.
This is the least common case. Usually all 3 matrices differ. Often we see M = AM or M = MB, but never M = MM.
With this revision mul_m4_m4m4 is called in exactly the same way but copies inputs only when needed. If you know the inputs are independent of the output use the "uniq" variant to skip the saftety checks.
This basically exposes to the UI a function that was only available
through a debug macro ; the purpose is obviously to help debugging
simulations. It adds ways to draw the vectors either as colored needles
or as arrows showing the direction of the vectors. The colors are based
on the magnitude of the underlying vectors.

Current approach uses view aligned slicing to generate polygons for GL
texturing such that the generated polygons are always facing the view
plane. Now it is also possible to use object aligned slicing, which
creates polygons by slicing the object perpendicular to whichever axis
is facing the most the view plane. It is also possible to create a
single slice for inspecting the volume, or for 2D rendering effects.
Settings for this, along with a density multiplier setting, are to be
found in a newly added "Smoke Display Settings" panel in the smoke
domain properties tab.

Using context.active_gpencil_brush to access the active Grease Pencil brush
would result in a crash if trying to rename the brush, because the "ID" pointer
was not set.
To be backported to 2.78
This is something what was guaranteed in give_current_material(), just
copied some range checking logic from there.
Not sure what would be a proper fix here tho.
In fact, it was the whole remapping process that was broken in logic bricks area,
due to terrible design of links between those bricks...
Object copying was also broken in that case, fixed as well.
To be backported to 2.78.
Note that issue was actually probably there since ages, hidden behind dirty hacks
used in previous append code (though likely visible in some corner cases).
Listen kids: do not, never, ever, do what has been done for links between logic bricks. Never. Ever.
Even as pure runtime data it would have been bad, but as stored data...
Optimization attempt with BKE_library_idtype_can_use_idtype() was not taking into account
the fact that drivers may link virtually against any datablock...
Has to be rethinked, but for after 2.78 release, this commit is safe to backport.
Regression caused by rBb27ba26, we would always tag datablocks to update in G.main,
ignoring given bmain, now always use this one instead.
To be backported to 2.78.
