Regression from rB036c006cefe471. We can't use self here, self is bpy.app, not pydescriptor of python path getsetter...
So for now, do not try to replace getsetter by actual value in bpy.app's dict,
just return static var generated on first run.
Should be safe for 2.78.
I) Filename was not put in temp Main generated to save selected data only,
this was breaking readcode when trying to open partial file, leading to missing
filename in final loaded Main data.
II) Read code would confuse partial .blend files with Undo ones, when they had no screen in them
(which happens to 99.999% of partial .blend files I guess).
Reported by @sybren, thanks.
Should be safe enough for 2.78 release.
The title says it all actually. From tests with barber shop scene here
gives 2-3x speedup for shader compilation on my oldie i7 machine. The
gain is mainly due to textures metadata query from jpeg files (which
seems to requite de-compression before metadata can be read). But in
theory could give nice improvements for scenes with huge node trees
as well (i'm talking about node trees of complexity of fractal which
we had reports about in the past).

The issue was caused by some false-positive empty non-AABB intersection.
Tried to tweak it a bit so it does not record intersection anymore.
Hopefully will work for all platforms. Tested here on iMac and Debian.
The idea is to allow certain animation channels to be always visible in
animation editors. So, for example, one can pin Camera animation to the
editor so it is always possible to refine/tweak camera animation when
animating something else in the scene.
There is probably some more polishing required, and some current
limitations could be solved in the future but should be a good starting
point already.
Currently only works for object without recursing into deeper datablock
(so for example, it's not possible to pin object material animation).

Basically just moves cached kernels from ~/.config/blender/BLENDER_VERSION to
~/.cache/cycles/kernels. This has following benefits:
- Follows XDG specification more closely,
not as if it's totally crucial or measurable by users, but still nice.
- Prevents unexpected sizes of config folder, makes disk space used in more
predictable for users way.
- Allows to share kernels across multiple Blender versions,
which makes it easier debugging at the times close to release.
- "Copy Previous Settings" operator will no longer be copying possibly
gigabytes of cached kernels, which used to lead to really nast disk usage
and annoying delays of copying settings.
- In the future we can have some smart logic to clear old unused cached
kernels.
Currently only done for Linux and OSX. Windows still follows old "cache"
folder logic, but it's not really important for now because we don't
support kernel compilation on this platform yet.

Constant folding was removing all nodes connected to the displacement output
if they evaluated to a constant, causing there to be no valid graph for
displacement even when there was displacement to be applied, and sometimes
caused crashes.
Using ones complement for detecting if transform has been applied was confusing
and led to several bugs. With this proper checks are made.
Also added a few transforms where they were missing, mostly affecting baking
and displacement when `P` is used in the shader (previously `P` was in the
wrong space for these shaders)
Also removed `TIME_INVALID` as this may have resulted in incorrect
transforms in some cases.

Bump mapping was happening in world space while displacement happens in object
space, causing shading errors when displacement type was used with bump mapping.
To fix this the proper transforms are added to bump nodes. This is only done
for automatic bump mapping however, to avoid visual changes from other uses of
bump mapping. It would be nice to do this for all bump mapping to be consistent
but that will have to wait till we can break compatibility.

Now the factor works similar to other Blender areas to make the factor
more consistent for artists. The value 0% means equal to original
stroke, 100% equal to final stroke (50% means half way). Any value below
0% or greater than 100% create an overshoot of the stroke.
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.
