The existing code uses the input value count of the first channel
for all of them. If the first channel is the largest, it leads to
a crash-causing buffer overrun in memcpy below. Likely this was
left since the time when only one channel was supported.
As a crash fix, probably should go into 2.78
This commits changes two things:
* It adds more keysyms preferably taken from XLookupKeysym than XLookupString (namely, all numpad ones).
* It falls back to keysyms from XLookupKeysym in other cases, when XLookupString does not produce anything we know of.
Finding the correct balance here is far from easy, but think we are comming rather close to it now...
Root of the issue is that active render index became wrong. This is the actual
thing to be fixed, but as usual this is quite tricky to reproduce. Since such
bad situation might have happened more and fix isn't really difficult or
intruisive let's avoid crash for now.
Can be revisited once we figure out root of the issue.
Nice for 2.78 release.
Own fault in new ID management work, thought rebuild the DAG itself was
enough to actually update whole scene, but we actually need to tag datablocks
for update as well, when we change (or remove) one of their ID pointers...
OCD commit, but cleans the code a bit:
- the first `if 0` block was supposed to draw collision objects but is
vastly outdated as most of the SmokeCollisionSettings member variables
were removed a few years ago and collision objects are drawn like other
objects anyway. Also it was committed already commented out back in
2009.
- the second `if 0` block was doing pretty much the same thing as the
few lines above it.
Most of the time, Lamps in Cycles are just a constant emission closure, no texturing etc. Therefore, running a full shader evaluation is wasteful.
To avoid that, Cycles now detects these constant emission shaders and stores their value in the lamp data along with a flag in the shader.
Then, at runtime, if this flag is set, the lamp code just uses this value and only runs the full shader evaluation if it is neccessary.
In scenes with a lot of lamps and with "Sample all direct/indirect" enabled, this saves up to 20% of rendering time in my tests.

For proper indexing to work we need to use unaligned node with
identity transform instead of aligned nodes when doing refit.
To be backported to 2.78 release.
This is really hack-fix actually, not sure why `get_pointcache_keys_for_time()` seems to assume
it will always find key for given part index at least for current frame, and whether this assumption
is wrong or whether bug happens elsewhere...
Anyway, this is to be wiped out in 2.8, so no point loosing too much time on it, for now merely
returning unchanged (i.e. zero'ed) ParticleKeys in case index2 is invalid. Won't hurt anyway,
even if this did not crash in release builds, would be returning giberish values.
Weirdly enough, this version of XCode seems to have static_assert()
even when NOT using C++11. This is totally weird and counter intuitive
since static_assert() is supposed to be C++11 onlky feature.
Can XCode stop using future, please? :)
The two SVM nodes added with e7ea1ae78c caused a slowdown on AMD cards when rendering with OpenCL, whether displacement was used or not.
In the Barcelona Pavillon scene on a RX480, this would cause a 12% slowdown.
Therefore, this commit adds a additional flag for feature-adaptive compilation so that the new SVM nodes are only enabled when they are needed (Node tree connected to the Displacement output and Displacement type set to Both).
Also, the nodes were also added to shaders when the Displacement Type was set to Bump (the default), which was unneccessary and is fixed now.
Thanks to linda2 on IRC for reporting and testing and to maiself for help with the displacement shader code.
This fix might be relevant for 2.78, but it should be tested further before including it.
When drawing with Grease Pencil "continous drawing" for a long time
(i.e. basically, drawing a very large number of strokes), it could be
possible to cause lower-specced machines to run out of RAM and start
swapping. This was because there was no limit on the number of undo
states that the GP undo code was storing; since the undo states grow
exponentially on each stroke (i.e. each stroke results in another undo
state which contains all the existing strokes AND the newest stroke), this
could cause issues when taken to the extreme.
See commit's comments for details, but this boils down to: do not try to use
purely runtime cache data as a 'real' ID pointer in readcode, it's likely
doomed to fail in some cases, and is bad practice in any case!
Thix fix implies dupliweight's object will be invalid until first scene update
(i.e. first particles evaluation).
Two new modal operators to create a grease pencil interpolate drawing
for one frame or a complete sequence between two frames. For drawing
the temporary strokes in the viewport, two drawing handlers have been
added to manage 3D and 2D stuff.

The operator shortcuts are Ctrl+E and Ctrl+Shift+E. During the modal
operator, the interpolation can be adjusted using the mouse (moving
left/right) or the wheel mouse.
Could not reproduce it here, but since users having the issue claims it comes from
rB16cb9391634dcc50e, let's try to use again ugly `XLookupKeysym()` for those modifier keys too...
Cpack generates a standard filename with git information in it, which might not always be wanted for release builds, this patch adds an option to override that default filename.

This commit caused some flickering in the bones when swapping IK to Fk.
While it's unclear why such change caused any regressions, let's revert
it to unlock the studio.

Based on reading documentation around. This particular version
is based on the ImageMagic documentation which could be found
there:
http://www.imagemagick.org/Usage/filter/http://www.imagemagick.org/Usage/filter/nicolas/
Current filter is based on measuring mean error with the current
splash screen and choosing combination of parameters which
gives minimal mean error.

In User Preferences, Properties Editor and toolshelf, Ctrl+Tab and Ctrl+Shift+Tab now activates the next or previous space context (or category in case of toolshelf tabs), respectively.
For Properties Editor such functionality was completely missing, only toolshelf allowed cycling using ctrl+mousewheel (or only mousewheel while hovering tab region). Ctrl+Tab and Ctrl+Shift+Tab are common web browser shortcuts, so they're a reasonable choice to go with.
Reaching the first/last item doesn't cause the cycling to stop, we continue at the other end of the list then. (I didn't add this to Ctrl+Mousewheel toggling in toolshelf since I wanted to keep its behavior unchanged.)
We could get rid of (Ctrl+)Mousewheel cycling in toolshelf, but this may break user habits.
The cycling happens using a new operator, UI_OT_space_context_cycle, for toolshelf tabs it's hardcoded in panel handling code though.
Generalized rna_property_enum_step a bit and moved it to rna_access.c to allow external reuse.

This is a bug in the multithreaded task manager in negative value range.
The problem here is that if previter is unsigned, the comparison in the
return statement is unsigned, and works incorrectly if stop < 0 &&
iter >= 0. This in turn can happen if stop is close to 0, because this
code is designed to overrun the stop by chunk_size*num_threads as
the threads terminate.
This probably should go into 2.78 as it prevents a crash.
Based on patch by @codemanx, but with slightly less verbose descriptions.
More detailed behavior etc. rather belongs to doc/python_api/examples/bpy.ops.x.py imho.
Was incorrect indexing done in the array. Caused by 5abae51.
Not sure why it needed to be changed here, but array here is supposed to be
a loop data, so bringing back loop index as it originally was. The shading was
wrong in edit mode with BI active as well (so it's not like it's needed for
BI only).
Patch in collaboration with Alexander Gavrilov (angavrilov), thanks!
Should be double-checked and ported to 2.78.
