When using multiple portals, scene areas behind one of the portals were rendered darker than they should.
The reason for that is a pretty stupid mistake: Since portals are only used at positions that aren't behind them,
only portals that are used should be accounted for in the PDF calculation. That was actually the case, but the final
divide incorrectly divided by the total amount of portals, not the amount of visible ones.
Another issue with areas behind portals was the PDF evaluation function.
The new evaluation code is shorter, simpler and fixes this issue.
Also, the threshold for the distance check was increased to avoid artifacts where portals touch a surface.
Regression from rB2dba2b3d71d9781bce45. Do not understand why MSVC needs this convoluted
allocation (looks like broken compiler crap?), but at least let's do it correctly!
Now a 'More' item is added to the pie when there are too many items. It opens a sub-pie that contains the remaining items.
Note that this only touches operator-enum pies (like the object mode pie is), it is not a complete support for pies with more than 8 items. For this further design and code work would be needed, but this is too urgent to wait for that.
This is a better fix for T46973, should definitely be applied for 2.77 release.
Patch D1800 by myself with some edits by @campbellbarton, thanks!
While it's not something we'll be using for the official release,
it's nice to support new libraries at least on "it compiles" level,
so it's not that many frustrated developers around.
Nexyon, please have a look into Audaspace changes :)
Supports both smoke/fire and point density textures now.
Reduces number of textures available for sm_20 and sm_21, but you have
to compromise somewhere on such a limited hardware.
Currently limited to linear interpolation only, and decoupled ray
marching is not supported yet. Think those could be considered just a
further improvement.
Some quick example:

Code is minimal and we can fully consider it a fix for missing
support of 3D textures with CUDA.

BKE_main_id_tag_/BKE_main_id_flag_ were horrible naming now that we split those
into flags (for presistent one) and tags (for runtime ones).
Got rid of previous 'tag_' functions behavior (those who were dedicated shortcuts
to set/clear LIB_TAG_DOIT), so now '_tag_' functions affect tags, and '_flag_'
functions affect flags.
This made byte & float images behave differently, where other modifiers remain the same.
Also remove scene from the modifier (should have been passed as arg but no longer needed).
Based on an user feedback, previous implementation with providing
decoupled X and Y speeds didn't work in production at all: there
is no way to combine this speeds to an usable vector.
So now we're providing speed vector output instead, which provides
speed in an exactly the way Vector Blur node expects it to be:
first two components is a speed from the past, second two components
defines speed to the future.
Old behavior can be achieved by RGBA separating the speed output
and using first tow components.
Now this speed gives quite the same results as a speed pass, with
the only difference that track position speed uses "shutter" of
1 while pass uses shutter of 0.5 (and there's no way to affect on
that?).
The issue was caused by static vectors allocating some internal
data using rebound element allocator for them, which was causing
access to a non-initialized statistics objects and was failing a
lot when switching Blender to a fully guarded allocation.
Additionally, we were not able to free that internal memory before
Blender exits, which was causing false-positive memory leak prints.
Now we're not using GuardedAllocator for those proxy containers.
Ideally this should be done as a GuardedAllocator::rebind, but
it didn't work for vector<bool> because it seems some internal
parts are converting bool to char32_t, which either makes it so
we can't use GuardedAllocator for those vectors or the compiler
get's confused when we're trying explicitly allow GuardedAllocator
for rebind<char32_t>.
This with current approach we should be fine for the release.
Python name could include ABI-flags after the version,
since checking for all combinations of ABI flags can expand into many possibilities,
take the executable name from the build system.
Was caused by some safety things of making sure we've for NULL
terminator for the buffer when doing mbs<->wcs conversion, but
it turns out this simply confuses str::string and it can no
longer have proper .size(). Let's assume behavior of string
allocation is same all over the std, and we can avoid having
that extra null-terminator allocated.
