Fixes for clamp-omp, fewer shared variables, fix some cases of threads writing
to the same memory location. Issue found by Jens Verwiebe, who reports 30%
speedup with 16 core CPU, when using this with a recent clang-omp version.
Transition away from GLU and legacy matrix stack. Using point sprites eliminated the need for most of the matrix math!
Depends on decent support of large aliased points. NVIDIA is good at this, must test limits on AMD & Intel systems.
Still needs proper scaling based on view zoom.
Part of T49042, touches on T49043 and T49450.
Apparently GL_POINT_SPRITE is important to GL 3.2+ compatibility profile, not just to GL 2.1 as thought.
We'll remove this during the core profile transition.
- Explicitly specify the platform for msbuild, to facilitate builds with just the Visual C++ Build Tools installed.
- When vs2013 is not found, try looking for 2015 as a fallback
- Clear up any batch variables that might have been set from previous runs
This is also an important mathematical operation that can be folded
if it is known that one argument is a certain constant. For colors
the operation is provided as a Gamma node.
The SVM Gamma node needs a small fix to make it follow the 0 ^ 0 == 1
rule, same as the Power node, or the Gamma node itself in OSL mode.

At context startup, make sure our assumptions about the OpenGL version are true. Should match since we set up the contexts... but this is what asserts are for, to check "should"s!

'camera' Object pointer of TimeMarkers is a 'temp' hack since Durian project...
Would need to be either made definitive now, or removed/reworked/whatever.
But since we intend to use that object pointer for other needs, and current code
could lead to crashing .blend files, for now let's fix that mess (was missing
some bits in read code, and also totally ignored in libquery code).
Should be safe for 2.78a.

Notes from drawvertsN function:
this used to be called twice (once for selected/active, once for unselected -- guess: to avoid state switches[color]?)
this used to be called in a loop, too (subcurves), moved the loop here to avoid multiple init stuff
Part of T49043
It will discard the whole tile, but it's still kind of more friendly than
fully locked interface (sort of) for until tile is fully sampled.
Sorry if it causes PITA to merge for the opencl split work, but this issue
bothering a lot when collecting benchmarks.
This change makes it so that when the sequences within a Scene strip are
evaluated, they use the Scene that they come from as the context as opposed
the Scene that the Scene strip is in. This is necessary, for example, in the
case of the MulticamSelector where it needs to reference strips in the original
Scene as opposed to the Scene where the Scene strip is located.
Patch by @Matt (HyperSphere), thanks!
Previously it was falling back to just a path after #include
statement was finished. Now we fall back to a proper current
file name after dealing with the preprocessor statement.
Some of the files were wrongly attributing code to some other
organizations and in few places proper attribution was missing.
This is mainly either a copy-paste error (when new file was
created from an existing one and header wasn't updated) or due
to some refactor which split non-original-BF code with purely
BF code.
Should solve some confusion around.
- The build folder name used to be depended on the order of the parameters, this is now normalized to
"build_windows_[Release/Full/Lite/Headless/Cycles/Bpy]_[x86/x64]_vc[12/14]_[Release/Debug]" regardless of the order of the parameters.
-Use CUDA8 for all kernels when building the release convenience target with visual studio 2015
In Windows, event dispatching code is throwing out the wheel scroll count value.
Despite of how many fast you move the wheel, it only make one-notch scroll event.
This patch convert wheel event to multiple 1-notch wheel events.
This also correct the handling of smooth scroll mouse wheel (which can report smaller than 1-notch wheel movement) by accumulating the small wheel delta values.

Another case of float imprecision leading to endless loop. INcreasing a bit 'noise threashold' seems to work OK.
Not a regression, but might be nice to have in 2.78a.
Not sure where this comes from, but code was converting BMEdge* to BMVert* to check oflags,
i.e. not accessing correct memory.
Regression, to be backported to 2.78a.
Apparently the keying sets system doesn't support subclassing
KeyingSetInfo subclasses. I have added a note to the top of the file to
indicate this to future developers.
Regression caused rBbcc863993ad, write code was assuming dw->ob was always valid,
wich is no more the case right after reading file e.g.
Another good example of how bad it is to use 'hidden' dependencies between datablocks. :(
And another fix to be backported to 2.78a. :(((
Previously the pose library used the WholeCharacter key set, which ignores
selection and add keys for almost all bones in the rig. This is a very
slow operation on complex rigs. With this patch, only selected bones are
keyed, defaulting to keying all bones when none are selected.
Note that this fixes the FIXME previously mentioned in the source.
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.
