it was caused by ee5f432. Not sure why exactly blender runs into
threading conflicts here since material preview works.
Let's keep it simple for now and disable material nodes preview,
because it's not supported by the interface anyway.
This is to be included to the final release.
Added a lock to the Main which is getting acquired and released
when modifying it's lists.
Should not be any functional changes now, it just means Main is
now considered safe without worrying about locks in the callee.

- higher contrast between tip text and py-text
- use monospace for py-text
D611 by Severin, design by Plyczkowski, with own minor changes.
This is needed because render threads would do some allocations like
part buffer allocation and so. This is likely harmless with the lock
free allocator (not on Windows tho), but when using guarded allocator
we need to be sure access to the list of MemHead is safe.
This revision is meant to update Freestyle's Python scripts to make full usage
of the new features of Python and Freestyle's Python API.
Freestyle's Python scripts are pretty old already, and were never given much
attention. With the 2.7x generation of Blender coming up, this is an excellent
time to update Freestyle's Python scripts, hopefully adding some new features
and achieving some speed improvements on the way.
Main goals:
* use for loops where possible
* general cleanup, making use of more recent python features (generators,
ternary operator, ect.)
* update the documentation on the way (it's lacking atm)

Don't know when this sneaked in, I did wrote that part of the patch on win VM with MSVC2013... :/
Note: letting asside warnings for now, then should not prevent building anyway.

Patch by @Severin (with minor modifications by me). As discussed in
{D535} the node editor does not have real modal operator tools like the
3D view or image editors for instance, so it makes sense to utilise it
this way. Tabs really help in this area due to the large amount of node
types and categories. Further tweaks could be made later if the need
arises.
Current temporary data of Blender suffers one major issue - default 'temp' dir on Windows is never
automatically cleaned up, and can end being quite big when used by Blender, especially when we have
to store per-process data (using getpid() in file names).
To address this, this patch:
* Divides tempdir paths in two, one for 'base' temp dir (the same as previous unique tempdir path),
the other is a mkdtemp-generated sub-dir, specific to each Blender instance.
* Only uses base tempdir when we need some shallow persistance accross Blender sessions - and we always
reuse the same filename (quit.blend...) or generate small file (crash reports...).
* Uses temp sub-dir for heavy files like pointcache or renderEXRs (Save Buffer option).
* Erases temp sub-dir on quit or crash.
To get this working it also adds a working 'recursive delete' to BLI_delete() under Windows.
Note that, as in current code, the 'recover render result' hack-feature that was possible
with SaveBuffer option is still removed. A real renderresult cache feature will be added
soon, though.

This way we only catch exceptions which we're intended to
and if something bad happens (like missing import due to
refactor or so) we'll see them instantly.
* Fixed different not-in-sync #ifdef blocks for struct stat variants under Windows.
Comments have been left to indicate the portions of BLI_fileops.h and
BLI_fileops_types.h that need to stay in sync.
* Added BLI_wstat() to de-duplicate #ifdef blocks for stat() variants on Windows.
* Fix for opendir() and associate functions in MinGW not working properly with
non-ASCII, MBCS-compatible paths.
MinGW (FREE_WINDOWS) has opendir() and _wopendir(), and only the
latter accepts a path name of wchar_t type. Rather than messing up with
extra #ifdef's here and there, Blender's own implementations of opendir()
and related functions are used to properly support paths with non-ASCII,
MBCS-compatible characters.
Tested with MSVC 2013 Express, MinGW32 (gcc 4.6.2) and MinGW-w64 (gcc 4.7.1).

It turns out that the new Beckmann sampling function doesn't work well with
Quasi Monte Carlo sampling, mainly near normal incidence where it can be worse
than the previous sampler. In the new sampler the random number pattern gets
split in two, warped and overlapped, which hurts the stratification, see the
visualization in the differential revision.
Now we use a precomputed table, which is much better behaved. GGX does not seem
to benefit from using a precomputed table.
Disadvantage is that this table adds 1MB of memory usage and 0.03s startup time
to every render (on my quad core CPU).
