Patch by Yasuhiro Fujii, thanks!
Original issue was that in vases viewport's lens are different from default
value switching between perspective and orthographic projections will change
viewplane a lot, which is disorienting and annoying.
Patch by Sebastian Nell, thanks!
Still not ideal (it could some smarter selection policy in such case perhaps),
but it's less annoying than it was before.
Using "outliner data operation" on vertexgroup suggested it should work, but this is not
supported yet. Similar to all the other cases it throws a Report warning now.
This time issue was caused by Save Buffers enabled and the reason blender
crashed was tiles generated by cycles didn't match tiles generated by
openexr.
Currently solved it in a way that background rendering will allocate tiles
in the same way render parts are generated in blender. Viewport rendering
will still be using sliced image, but it's more tricky to change and it's
no so big deal for now.
You don't believe it, this bug traces back to 2002. Went by unreported for a decade.
If you link in an object, delete it, and relink again its materials are lost!
Easy fix, annoying error. :)
Problem here is that muted nodes and reroute nodes are supposed to be removed from the execution node tree during the localize function. However, this is function is apparently only used during preview renders and must be considered a hack (is there anything that is not a hack in BI?)
Now the mute/reroute check happens in the node tree exec functions still used by BI and the legacy compositor and texture nodes. It uses the same internal_connect function from nodes to assign input stack indices directly to outputs (which also avoids overhead). Localize function also still does this. Cycles/Tile should also implement muting/reroute in their intermediate node layers by using this function, then it could be removed from localize too.
It is not a well-supported feature of the primary node systems (shader, compositor, texture) in Blender. If anybody wants to create a node system that has actual use for loops, they can do so much more elegantly with Python nodes, but it does not have to be a core node type in Blender. Removing this should ease node code maintenance a bit.
Text object render error.
Issue was caused by FLT_EPSILON being used to check for zero-sized faces, for
getting a reliable normal of front/backfaces of polygons. This value is too
small, giving occasional bad looking faces.
In other parts of code FLT_EPSILON10 was being used, that works much better.
Note for the future: here using doubles internally would be advised.
This makes it possible to create pixelized scale in the Tile compositor.
Just append the node in front of a scale node or where you want the pixelization to take place.
There were some bugs on this subject, but they used the work around to add a blur size of 0 in the place where they need the pixelization.
* In some cases a quad would be intersected twice so particles near this double-intersection point were not generated in grid distribution due to being marked as outside the surface.
* Bullet's convex hull implementation is significantly more robust
than the one I implemented, as well as being faster.
* This fixes bug [#32864] "Convex Hull fails in some cases."
projects.blender.org/tracker/?func=detail&aid=32864&group_id=9&atid=498
That bug, and others like it, relate to the poor handling of
co-planar surfaces in the input. Pretty much any model that is
simple-subdivided a few times gave very bad results before, Bullet's
implementation handles this much better.
* In order to ensure a smooth transition, the Bullet output is
translated into the existing HullTriangle hash structure. This makes
it easy to ensure that the existing slot output stays the same; the
interactions between the slots are somewhat complicated, detangling
is a TODO.

* Add access to the original indices for vertices
* Add a very simple C API for convex hull
* Add this patch to the patches folder and update readme.txt
I though allocating zero-sized mem would return a NULL pointer, but it looks like it does not... :/ Anyway, Blender should no more crash in case languages file is missing, will just use default (system) locale...
Issue was caused by offline rendering could have been allocated the same tile
to different devices and in this case buffers would become invalid.
Made it more clear in the code, so now it's flag for tile manager to indicate
whether tiles should always be allocated for the same device or not.
Also cleaned a way how tile index for progressive refine is calculating,
which is now avoids tricky computation based on tile coordinate and it's
dimensions.
