Faces that have the last two indices equal are considered triangles, and not those that the last index is 0
Improvement of 7% in performance of the `polygonize` function
Before this patch, the XBlur/YBlur compositor nodes would crash for me when run in a MSVC 2015 debug build (test scene: BMW27_cpu). I added the compiler instructions to explicitly align the local variables that the SSE instructions are accessing.
This was wrong since it's concenption in 28ee0f9218.
The if statement was returning true when pinid was NULL, and false otherwise.
However when scene is pinned we also want to run this code.
Code snippet by Brecht Van Lommel.
* Fix saving a multiview render from the image editor giving invalid files.
* Fix failure to load multiview images with a single view per part.
* Fix loss of multiview metadata when saving/loading a single view.
* Fix Z-Buffer writing option for single layer EXR not being respected.
Multiview EXRs are now always handled as multilayer internally, significantly
reducing the amount of code.

The algorithm averages normals from nearby surfaces. It uses the same
sampling strategy as BSSRDFs, casting rays along the normal and two
orthogonal axes, and combining the samples with MIS.
The main concern here is that we are introducing raytracing inside
shader evaluation, which could be quite bad for GPU performance and
stack memory usage. In practice it doesn't seem so bad though.
Note that using this feature can easily slow down renders 20%, and
that if you care about performance then it's better to use a bevel
modifier. Mainly this is useful for baking, and for cases where the
mesh topology makes it difficult for the bevel modifier to work well.

To help diagnose issues like T53259, it is useful to know the module causing the issue (is it us, or some opengl icd, or python module?) and while we cannot do stackdumps on release builds on windows, it is possible to display the faulting module. This commit changes the exception handler to output the following information:
Error : EXCEPTION_ACCESS_VIOLATION (Type of exception , this we had before)
Address : 0x0000000140193726 (Address of the exception, new)
Module : k:\BlenderGit\build_windows_Full_noge_x64_vc15_Release\bin\Release\blender.exe (module of the exception, new)
This makes code closer to id_override/assent-engine ones, which
introduce a new type of linked data, and hence reserve
ID_IS_LINKED_DATABLOCK to real linked datablocks.
Inner DAG code would not check against NULL pointer, and in case of an
active linked scene, scene pointer will be NULL here, so we have to
check it ourself. ;)
